No patches. But, I do override GCC default build options and use
"-g -O" for all stages. I also have
% valgrind --leak-check=full -s ${PATH}/f951 a.f90

This is on FreeBSD, which does not use glibc. So, perhaps, an issue with
something coming out of libc (e.g., malloc).
Note, this bug report conflates issues with source-expr (i.e., those in
comment #0) and an invalid character type-spec (i.e., code in coment #1).
The patch in
https://gcc.gnu.org/pipermail/fortran/2025-January/061559.html
fixes the former. The latter seems to be fixed.
