Strange segmentation faults of 3 SPEC_CPU_2017 fprate benchmarks

Hi guys,

I compiled and statically linked binaries from the SPEC CPU 2017 benchmark suite. But there are three fprate benchmarks always giving strange segmentation faults. They are '503.bwaves_r', '521.wrf_r' and '527.cam4_r', and the following is the 503.bwaves_r error message. Could anyone shed light on the root cause of the issue and how it can be resolved?

The ICC version is 17.0.4. The flags that I used for compilation and linking are as follows: 

  • LDCFLAGS        = -static -mkl -static-intel
  • SSE            = -xCORE-AVX2
  • OPTIMIZE       = $(SSE) -static -ipo -O3 -no-prec-div -qopt-prefetch -auto-p32 -ansi-alias

Thanks a bunch!

Don

Can you rebuild with an additional -g flag, so that if SIGSEGV occurs, it would give you more info.
