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

[Daniel Sanders via llvm-dev]

Thanks. From the debugging I've done so far it looks like it could be another 32-bit big-endian specific bug. 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.

This is quite sad as we can't reliably fix this case with the static
asan runtime.
I've disabled the test on mips.
