Segmentation fault

In fact segment fault caused by function "mbsrtowcs". I call this function in my PC machine(ubuntu 10.04,x86-32) and segment fault arise too.
Comment 1 Xiaofeng Yan 2011-05-18 04:32:28 UTC 
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.
