Public bug reported:
When building llvm-toolchain-3.3 on saucy i386, the build hangs in the test
phase, and outputs a message about malloc memory corruption. The message seems
to bypass the log file.
I looked up the process hanging in /proc, and executed its environ + cmdline
outside of the build process:
