--- Comment #2 from Vittorio Zecca <zeccav at gmail dot com> --- 1) No explicit options, just the default ones, -S will suffice. 2) Sorry, I did not specify the target is x86-64, but I got the same with -m32 3) sub is not needed, the code should just be compiled to exhibit the bug I have a sanitized (-fsanitize=address -fsanitize=undefined) version of gfortran. In the comments I put the output message from the sanitizer during compilation. What happens is that the pointer retargs is NULL. I believe this is bad. This fragment of code from gfc_conv_procedure_call is thus erroneous because it dereferences a null pointer. I did double check it by putting gcc_assert(retargs); immediately before its dereferencing. I then got an ICE at that line.
