[issue33174] compiler error building the _sha3 module with Intel 2018 compilers

2018-06-20 Thread Kenneth Hoste


Kenneth Hoste  added the comment:

Fully agreed that this is not something that should be fixed in the Python code 
base.

Moreover, the problem has been fixed in Intel compilers 2018 update 3 as far as 
I can tell (tested with both Python 3.6.4 and 3.7.0rc1).

I can't reproduce the problem anymore with that version of the Intel compilers, 
even after setting a hard stack limit (e.g. "ulimit -s 10240"), while it was 
easy to reproduce with the 2018 update 1 version.

[issue33174] error building the _sha3 module with Intel 2018 compilers

2018-06-20 Thread Kenneth Hoste


Kenneth Hoste  added the comment:

After a bit of back and forth, we have figured out the underlying cause for the 
problem with the Intel compiler: if the stack limit is not set to a specific 
value (see output of "ulimit -s"), the Intel compilers fail with a segfault or 
Interal Compiler Error (ICE).

But if the stack limit is set to 'unlimited' (e.g. via "ulimit -s unlimited"), 
then the compilation works fine...

Willian: on which OS and (Intel?) processor generation are you seeing this?

We're not seeing this on CentOS 7.4.1708 with Python 3.6.4 and icc 18.0.1.163 
on Intel Haswell or Intel Skylake.
We have seen this with other software on Intel Skylake though...

Have you tried with icc 18.0.2 (which was released March 21st 2018)?

Kenneth Hoste  added the comment:

@William: someone in the EasyBuild community seems to have figured out the 
culprit, and came up with a patch to work around the problem, see 
https://github.com/easybuilders/easybuild-easyconfigs/pull/6447/files#diff-bdbfca2206414b3b37794b77c0abb8e8
 .

Any feedback on that?
