[llvm-dev] buildbot failure in LLVM on clang-cmake-mips

[Evgenii Stepanov via llvm-dev]

The stack trace look very similar to the original problem on
linux/x86, which was due to mismatching symbol versions between
pthread_attr_* calls (unintercepted, binding to the default version)
and pthread_create (intercepted, binding to the lowest version through
dlsym).

It seems to be segfaulting in the memset() in allocate_stack.c (from glib) because given stack pointer is null. I'm guessing this is because it read the wrong half of a 64-bit value somewhere but I haven't identified where it goes wrong.
