Intel C++ 17 and gcc 4.8.2 compiler crashes

[Jussi_L_]

Hi,

After upgrading the Intel C++ Compiler from 14.0 to 17.0 in Linux, some parts of our code started to generate the following compiler crash when compiling the optimized (-02) build:

* Segmentation violation signal raised. *
Access violation or stack overflow. Please contact Intel Support for assistance.

- Environment: RHEL6, devtoolset-2 (which uses gcc 4.8.2)
- The crash only happens in (-02), not in (-01) nor in debug.
- Some crashes have been narrowed down to cilk_for-loop and go away when using regular for-loop.

Are there known issues with gcc 4.8.2? With cilk? Is that too old? Crashes also seem to go away when using newer gcc-version, but ideally we would not change due to all third party library dependencies.

Thanks!

Hi Jussi,

Can you identify a source file which failed to compile, then generate a pre-processed file for us to investigate?

Thanks,
