Hi,

Compiling the C++ program below fails with the error message shown. I am using NVHPC SDK 24.11 on Ubuntu 24.04.1 LTS.

#include <immintrin.h>
__m128 A[1] = {};

$ nvc++ -c -V24.11 nvcpp-bug-zero-init.cpp 
NVC++-F-0000-Internal compiler error. dinit: missing sub-initialization       0  (nvcpp-bug-zero-init.cpp)
NVC++/x86-64 Linux 24.11-0: compilation aborted

Cheers,
Paul

Thanks Paul.

I was able to recreate the issue and have filed a problem report, TPR#37004.

Hi Paul,

Engineering let me know that TPR#37004 was fixed in our 25.3 release.

Thanks again for the report.
