I call this function in my PC machine(ubuntu 10.04,x86-32) and segment fault arise too. 13865 1 Xiaofeng.yan 2011-05-18 04:32:28 +0000 I solve this bug by disabling time "UTC" on target environment,default is "UTC". Because there are two branches in test program, if target's time environment is "UTC", then function "mbsrtowcs" will be called with segment fault. if time environment is other standard time. then this function can't be called. Please check http://git.pokylinux.org/cgit.cgi/poky-contrib/commit/?h=xiaofeng/lsb&id=fadb1ec52c31b89379fca3880e7f00fad0222565 It could be not a good method to solve this bugs. So if anyone has a better solution, I will adopt it. If this patch can't be passed, then I mark this bug here for solving it later. 13938 2 sgw 2011-05-20 14:26:58 +0000 http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=720b5dbc0854b04151c2d42f58ad1360cd61a78f 27381 3 kai.kang 2012-11-13 07:34:34 +0000 Test case passes now without the patch. 158 2011-05-18 04:01:23 +0000 2011-05-18 04:01:23 +0000 test program from core test wcsftime.c text/x-csrc 3069 Xiaofeng.yan I2luY2x1ZGUgPHN0ZGlvLmg+CiNpbmNsdWRlIDxzdGRsaWIuaD4KI2luY2x1ZGUgPHN0cmluZy5o PgojaW5jbHVkZSA8Y3R5cGUuaD4KI2luY2x1ZGUgPHRpbWUuaD4KI2luY2x1ZGUgPGxvY2FsZS5o PgojaW5jbHVkZSA8d2NoYXIuaD4KI2luY2x1ZGUgPHdjdHlwZS5oPgoKI2RlZmluZSBTVFJfTEVO R1RIIDI1NgoKLy9jaGFyICp0ZXN0X2xvY2FsZSA9ICJMVFBfMS5VVEYtOCI7CmNoYXIgKnRlc3Rf bG9jYWxlID0gInpoX0NOLlVURi04IjsKCnN0cnVjdCB0bSB0ZXN0X3RpbWUgPSAKewogICAgMTIs CSAgLyogc2Vjb25kcyAqLwogICAgMzAsCSAgLyogbWludXRlcyAqLwogICAgMTYsCSAgLyogaG91 cnMgKi8KICAgIDIxLAkgIC8qIGRheSBvZiB0aGUgbW9udGggKi8KICAgICA0LAkgIC8qIG1vbnRo ICovCiAgIDEwMSwJICAvKiB5ZWFyICovCiAgICAgMSwJICAvKiBkYXkgb2YgdGhlIHdlZWsgKi8K ICAgMTQwLAkgIC8qIGRheSBpbiB0aGUgeWVhciAqLwogICAgIDAgICAgLyogZGF5bGlnaHQgc2F2 aW5nIHRpbWUgKi8KfTsKCndjaGFyX3QgZGVmX2Fid2RheVtdICAgICAgICAgPSB7MHgyNTBGLCAw eDI1MTMsIEwnXDAnfTsKd2NoYXJfdCBkZWZfZnVsbHdkYXlbXSAgICAgICA9IHsweDY3MTIsIDB4 MDA3RCwgMHg2MTAxLCBMJ1wwJ307CndjaGFyX3QgZGVmX2FibW9udGhbXSAgICAgICAgPSB7MHgz MDQ0LCAweDMwNDMsIEwnXDAnfTsKd2NoYXJfdCBkZWZfZnVsbG1vbnRoW10gICAgICA9IHsweDc2 OTAsIEwnXDAnfTsKd2NoYXJfdCBkZWZfZF90X2ZtdFtdICAgICAgICA9IHtMJzInLCBMJzAnLCBM JzAnLCBMJzEnLCAweDMwODEsCgkJCQkgICAgICAgIEwnMCcsIEwnNScsIDB4MDBBRiwKCQkJCQlM JzInLCBMJzEnLCAweDAwQzAsCgkJCQkJTCcgJywKCQkJCQlMJzEnLCBMJzYnLCAweDAwNzMsCgkJ CQkJTCczJywgTCcwJywgMHgwMENELAoJCQkJCUwnMScsIEwnMicsIDB4MDExRiwgTCdcMCd9Owp3 Y2hhcl90ICpkZWZfZGF5ICAgICAgICAgICAgID0gTCIyMSI7CndjaGFyX3QgKmRlZl8yNGgJICAg ICA9IEwiMTYiOwp3Y2hhcl90ICpkZWZfMTJoCSAgICAgPSBMIjA0IjsKd2NoYXJfdCAqZGVmX3lk YXkJICAgICA9IEwiMTQxIjsKd2NoYXJfdCAqZGVmX21vbl9kZWMgICAgICAgICA9IEwiMDUiOwp3 Y2hhcl90ICpkZWZfbWludXRlcyAgICAgICAgID0gTCIzMCI7CndjaGFyX3QgZGVmX2FtX3BtW10g ICAgICAgICAgPSB7MHgzMDYxLCAweDAwNDcsIEwnXDAnfTsKd2NoYXJfdCAqZGVmX3NlY29uZCAg ICAgICAgICA9IEwiMTIiOwp3Y2hhcl90ICpkZWZfd2Vla19kZWNfcyAgICAgID0gTCIyMCI7Cndj aGFyX3QgKmRlZl9kYXlfb2Zfd2Vla19kZWMgPSBMIjEiOwp3Y2hhcl90ICpkZWZfd2Vla19kZWNf bSAgICAgID0gTCIyMSI7CndjaGFyX3QgZGVmX3ByZWZlcmVkX2RhdGVbXSAgPSB7TCcyJywgTCcw JywgTCcwJywgTCcxJywKCQkJCSAgICAgICAgTCcwJywgTCc1JywgMHgwMEFGLAoJCQkJCUwnMics IEwnMScsIDB4MDBDMCwgTCdcMCd9Owp3Y2hhcl90IGRlZl9wcmVmZXJlZF90aW1lW10gID0ge0wn MScsIEwnNicsIDB4MDA3MywKCQkJCQlMJzMnLCBMJzAnLCAweDAwQ0QsCgkJCQkJMHgzMDkxLCBM JzEnLCBMJzInLCBMJ1wwJ307CndjaGFyX3QgKmRlZl9kb3VibGVfeWVhciAgICAgPSBMIjAxIjsK d2NoYXJfdCAqZGVmX2Z1bGxfeWVhciAgICAgICA9IEwiMjAwMSI7CgovKiBWZXJpZnkgdGhpcyBm dW5jdGlvbiByZXBsYWNlcyBjb252ZXJzaW9uIHNwZWNpZmllciBgWicgd2l0aCB0aGUgdGltZQog ICB6b25lIG9yIG5hbWUgb3IgYWJicmV2aWF0aW9uLiAqLwppbnQgbWFpbiAoKQp7CiAgc2l6ZV90 ICByZXQ7CiAgd2NoYXJfdCBzdHJbU1RSX0xFTkdUSF07CiAgd2NoYXJfdCBkZWZfdGltZXpvbmVb U1RSX0xFTkdUSF07CiAgY2hhcgkgKnA7CiAgY2hhciAgIG1lc3NhZ2VbNjRdID0gIlRlc3QgTG9j YWxlIGlzICI7CiAgaW50ICAgIHBhdGhvayA9IDA7CiAgY2hhciAqZGVzYyA9ICJWZXJpZnkgdGhp cyBmdW5jdGlvbiByZXBsYWNlcyBjb252ZXJzaW9uIHNwZWNpZmllciBgWicgd2l0aCAiCgkgICAg ICAgInRoZSB0aW1lIHpvbmUgb3IgbmFtZSBvciBhYmJyZXZpYXRpb24uIjsKCiAgaWYgKHNldGxv Y2FsZShMQ19BTEwsIHRlc3RfbG9jYWxlKSA9PSBOVUxMKQogICAgewogICAgICBwcmludGYgKCJD YW5ub3QgdXNlIHRlc3QgbG9jYWxlLiIpOwogICAgfQoKICBzdHJjYXQgKG1lc3NhZ2UsIHRlc3Rf bG9jYWxlKTsKCiAgdHpzZXQoKTsKICBwID0gZ2V0ZW52KCJUWiIpOwogIGlmIChwID09IE5VTEwp CiAgICBwdXRlbnYgKCJUWj1VVEMiKTsgCiAgZWxzZQogICAgewogICAgICBjaGFyIHNbU1RSX0xF TkdUSF07CiAgICAgIGNvbnN0IGNoYXIgKipzcHA7CiAgICAgIG1ic3RhdGVfdCBzdGF0ZTsKCiAg ICAgIHN0cmNweSAocywgcCk7CiAgICAgIHByaW50ZigidGVzdDIxIiwgIm11bHRpYnl0ZSAlcyIs IHMpOwogICAgICBzcHAgPSAoY29uc3QgY2hhciAqKikmczsKICAgICAgbWVtc2V0ICgmc3RhdGUs ICdcMCcsIHNpemVvZiAobWJzdGF0ZV90KSk7CiAgICAgICh2b2lkKW1ic3J0b3djcyAoZGVmX3Rp bWV6b25lLCBzcHAsIFNUUl9MRU5HVEgsICZzdGF0ZSk7CiAgICB9CgogIHJldCA9IHdjc2Z0aW1l IChzdHIsIFNUUl9MRU5HVEgsIEwiJVoiLCAmdGVzdF90aW1lKTsKCiAgaWYgKHJldCA+IDApCiAg ICBpZiAocCAhPSBOVUxMKQogICAgICBpZiAod2NzY21wIChzdHIsIGRlZl90aW1lem9uZSkgPT0g MCkKICAgICAgICAgIHByaW50Zigib2stMSFcbiIpOwogICAgICBlbHNlCgl7CgkgIHByaW50ZiAo IlRoZSBzcGVjaWZpZXIgJVogaXMgbm90IGNvbnZlcnRlZCBjb3JyZWN0cnkuIik7Cgl9CiAgICBl bHNlCiAgICAgIGlmICh3Y3NjbXAgKHN0ciwgTCJVVEMiKSA9PSAwKQoJICAgICAgcHJpbnRmKCJv ay0yIVxuIik7CiAgICAgIGVsc2UKCXsKCSAgcHJpbnRmICgiVGhlIHNwZWNpZmllciAlJVogaXMg bm90IGNvbnZlcnRlZCBjb3JyZWN0cnkuIik7Cgl9CgogIGVsc2UKICAgIHsKICAgICAgcHJpbnRm ICgiVGhlIHJldHVybiB2YWx1ZSBpcyBub3QgY29ycmVjdCIpOwogICAgfQoKfQoK
