[Sbcl-devel] SBCL crashed when using multithreaded version of Intel MKL

[HUANG, J. <hu...@ms...>]

Hello,

Is there anyone succeeded in using the multithreaded version of Intel
MKL in SBCL? It crashed my lisp (segfault). I'm using SBCL 1.0.28.22
x86_64 on Linux.

I tried to debug using gdb but was unable to finish the program since
too many SIGSEGVs were signaled and didn't seems to stop. So I have no
idea why it crashed yet.

The source code for testing is attached with the email, but you need to
install Intel MKL first (and run the mklvarsem64t.sh script to
establish the environment). 

The multithreaded version of Intel MKL depends on Linux's pthread for
their openmp implementation. And I'm currently loading the
libmkl_gnu_thread.so for the threading layer, as according to the
documents this is the one that supports gnu compilers.

It will be very helpful if someone can give me some advice.



Cheers,
Jianshi
