Hi,
The latest version of glibc in the Plucky release pocket was released on
December 16th, it's not that new.
Furthermore, looking at the stack trace, you can see that the code
reenters glibc on __assert_fail, which indicates that the crash is due
to an assertion failure in the calling code, from Xorg. I'm assigning
that package to the bug.
The stack frames before the assert fail are related to DRI, so it might
be an issue in mesa or the kernel. Could you provide us with the full
system logs in the few seconds leading up to the the crash?
