The problem occurs even with a clean tree. I have filed PR65792 for it.
The test in comment 41 runs without error if compiled with -fsanitize=address
and no valgrind error if I remove/comment the lines 58 and 62:
tmpc = new_prt_spec2 (string_container_t(prt_in))
and
deallocate(tmpc%comp%chars)

I have bootstrapper 4.9.3 with the patch and I am currently regtesting
gfortran. I am planing to do that same for 5.0.1.
