Great. 58512 3 ross.burton 2016-02-03 17:16:35 +0000 So I've spend an hour poking at jethro and master in an attempt to replicate this and I can't seem to do it by hand, even less so inside a selftest. My best guess was a devtool reset wiping bits of the sysroot away, but that's never done against the native sysroot. The dependencies in qemu are fine so something must be going into the sysroot and breaking things. From what I can tell this hasn't happened again so maybe it was a transient failure with some broken tests? Reluctantly closing, we can re-open if it happens again. 58940 4 stanciux.mihail 2016-02-12 08:35:02 +0000 Hasn't happened again for 2.0.1_rc6. Marking verified.
