Package: gcc-13-offload-nvptx Version: 13.3.0-8 Severity: grave Justification: renders package unusable Dear Maintainer, Any attempt to compile code that offloads to nvptx-none fails with the following error: gmulas@capitanata:~/mintest$ gcc -fopenmp -O3 -ggdb -fcf-protection=check -foffload=default -foffload=nvptx-none="-O3 -ggdb -fopt-info -lm -latomic -mgomp" -o mintest mintest.c mintest.c:5:9: optimized: basic block part vectorized using 16 byte vectors collect2: fatal error: ld terminated with signal 11 [Errore di segmentazione], core dumped compilation terminated. nvptx mkoffload: fatal error: x86_64-linux-gnu-accel-nvptx-none-gcc-13 returned 1 exit status compilation terminated. lto-wrapper: fatal error: /usr/libexec/gcc/x86_64-linux-gnu/13//accel/nvptx-none/mkoffload returned 1 exit status compilation terminated. /usr/bin/ld: error: lto-wrapper failed collect2: error: ld returned 1 exit status This occurs with any gcc (or g++) version installable on debian sid, so I suspect it is connected to some update on the nvptx-tools side, but since it is reproduced using gcc I am initially reporting the bug on gcc-13-offload-nvptx. If/when you can trace it to some other package, of course feel free to move the bug where it belongs. This is rather critical, since it makes it impossible to compile any code that offloads to nvptx. I attach a minimal test code that reproduces it. It compiles and runs flawlessly on a debian stable machine.
