Hi Mike,

Can you please create a preprocess (sha3module.i), by replace -c with -E, and attach it to us to investigate?

Thanks,

Viet

[Nolta__Mike]

Sure, attached.

Thanks, I've reproduced the problem and will submit this bug to our developer for a fix.

Hello Viet,

did this fix make it into 2018.2?

Cheers, Peter

I was also seeing this problem with Intel compilers 2018 update 1, when building Python 3.6.4.

It turns out that there's a workaround for this: the underlying cause for the segmentation fault seems to be that there's a stack limit in place (see output of "ulimit -s"). You may be able to dance around the issue by setting the stack limit to unlimited using "ulimit -s unlimited" (whether that'll work depends on the hard limit, see "ulimit -s -H").

I'm not seeing this problem anymore when building Python 3.6.4 with Intel compilers 2018 update 3 with a stack limit in place, so it seems like the bug has been fixed in either 2018 update 2 or 3.
