Hi Vittorio,

Thanks for reporting the ICE.

We are looking into it and will get back to you soon.

Regards

Prasanth

[Viet_H_Intel]

Vector types work differently in LLVM compares to GNU. If you compile the test case with clang++ you would get the same error.

Thanks,

Viet 

[Viet_H_Intel]

I am going to close this thread as it is not an issue with icpx/clang++.

Thanks,

[vzecca]

I believe icpx should issue a meaningful and helpful error message as in

invalid vector element type 'int [sizeof(T)]' from clang++ version 12.

It should not crash with a request of a bug report.

[Viet_H_Intel]

Yes, you will see this message with the next update version.

t1.cpp:3:31: error: invalid vector element type 'int [sizeof(T)]'
int x[sizeof(T)] __attribute((vector_size(8)));

Thanks,
