Filed the bug with OpenBlas (https://github.com/xianyi/OpenBLAS/issues/716)
but they seem more inclined to think that something else corrupted the
memory and the problem only shows up in OpenBlas.
I have attached the backtrace for all the threads at the end. From
preliminary investigation it seems that "getenv" is not thread safe.
OpenBlas gets initialised on a separate thread and tries to access the
environment variable "GOTO_BLOCK_FACTOR" and I suspect that something else
on another thread might be calling "setenv".
Backtrace:

Given the backtrace this is almost certainly some sort of bug in
openblas, and I'd suggest filing a bug with them.
It's possible that we might have accidentally added a workaround in
1.10.2 (release candidate currently available, final should be out
soon). There was some environment variable handling code in numpy 1.9
through 1.10.1 that triggered problems in some buggy libraries (see
numpy issues #6460 and 6622); possibly the workaround for those issues
will also workaround this issue. But if not then I'm not sure what
else we can do, and it's probably a good idea to file a bug with
openblas regardless.
