Segmentation fault
« on: June 13, 2016, 05:26:03 PM »

I have a relatively long code that uses OpenMP  and parallelization (with the fastest options - I'm using Absoft 15) and all these commands are inside another simple loop that is not parallelized. Here is the issue:

The debug shows no error.
While compiling in the release mode, I get  Segmentation fault:

Segmentation fault
project.ipaZP3ZZC/makefile.ipa5867:31: recipe for target 'project.ipaZP3ZZC/2.o' failed
be reported errors.
make: *** [project.ipaZP3ZZC/2.o] Error 1
ipa_link reported errors.
amake2: **** Error code 1 (continuing)
amake2: `all' not remade because of errors.
Build interrupted

If I take out the simple loop that is not paralelized, the code will compile and run without any problem.  I have tried it on another node in our cluster and the code runs fine again but that node is using an older version, Absoft 14.

I  appreciate any help!

This error is a fatal failure in the compiler's inter-procedural optimization pass. Our developers
are going to need a way to reproduce this error before they can develop a fix. Please
send an email to our support group using  support at  to continue this further. 

In the short term, all I can suggest is reducing the optimization level to O3 to disable inter-procedural optimization.
