The boot failed with clang tool chain and PASS with gcc-13.

Are the UBSAN options getting enabled with GCC as well? I am somewhat surprised that they are not agreeing here, unless this is a __counted_by related issue? Does this not happen with GCC 14 as well? It would be nice if we could get a copy of GCC 15 with __counted_by into TuxMake for validation of __counted_by between the two compilers easily. I did not see any obvious instances of __counted_by in edma_probe() but admittedly, I did not look too hard.
Boot failed: clang-19 Configs: korg-clang-19-lkftconfig-hardening Boot pass: qemu-armv7 (Additional info)
This is always reproducible.

Can you turn off UBSAN_TRAP and see if that gives us any indication as to where exactly UBSAN_BOUNDS is triggering here? It is not entirely clear because we do not seem to have a line number in edma.c from decoding the stacktrace.

Hi Naresh,

The boot failed with clang tool chain and PASS with gcc-13.

Are the UBSAN options getting enabled with GCC as well? I am somewhat surprised that they are not agreeing here, unless this is a __counted_by related issue? Does this not happen with GCC 14 as well? It would be nice if we could get a copy of GCC 15 with __counted_by into TuxMake for validation of __counted_by between the two compilers easily. I did not see any obvious instances of __counted_by in edma_probe() but admittedly, I did not look too hard.

This is always reproducible.

Can you turn off UBSAN_TRAP and see if that gives us any indication as to where exactly UBSAN_BOUNDS is triggering here? It is not entirely clear because we do not seem to have a line number in edma.c from decoding the stacktrace.
Anders made a new build with UBSAN_TRAP turn off and the boot pass CONFIG_UBSAN_TRAP=n on arm TI x15 device.
