glibc 2.22 -- Final testing for 32-bit x86 failing?


Has anyone else done 32-bit x86 testing and had it work? Top of master
is showing some kind of problem with memory corruption.

memory clobbered past end of allocated block

Program received signal SIGABRT, Aborted.

Has anyone seen this? This appears to be new. I'll see if I can track
this down to an environment change in my build box (Fedora 21).
