clang: error: unable to execute command: Segmentation fault bug report

[keng420]

Wile compiling code for matrix matrix multiplication on a raspberry pi 3 I got an error massage asking to file a bug report. So here it is.

I also added the original program code if it helps.

compile command:

clang  -fopenmp -O3 matrix_multiplication.c -o matrix_multiplication

output:

PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.

@keng420 Does the problem reproduce with a bit more recent version of LLVM? E.g. LLVM 18?

[keng420]

No the problem does not reproduce in LLVM 18 and previously it was a problem with including arm_neon.h .

Thanks for the help.
