Internal compiler error: segmentation violation signal raised

shof — Tue, 20 May 2025 07:01:43 GMT

Hi,

I faced an Internal compiler error when I tried to compile my Fortran code. I will report this as the compiler told me to do. I attached a source file I tried to compile. The compile command I used is:

ifx -qopenmp report.F90

If I chose not to use OpenMP, the compilation went successfully. Also, if I used gfortran, the compilation was successful.

My environment:

OS: Rocky Linux 9.4

ifx version: ifx (IFX) 2025.0.4 20241205

Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit
Address sizes: 52 bits physical, 57 bits virtual
Byte Order: Little Endian
CPU(s): 384
On-line CPU(s) list: 0-383
Vendor ID: AuthenticAMD
Model name: AMD EPYC 9654 96-Core Processor

Best,

Sho

I found that the compilation went successfully if I commented out the "taskloop reduction" construct.

Hi,

We also found internal compiler error and started triaging it with development team.

Thanks.
