Another corner case of buffer overflows during name mangling found by Gerhard. We now check that the new buffer sizes suffice.The patch is on top of the patches for PRs 95687, 95688, 95689. Regtested on x86_64-pc-linux-gnu. OK for master / backports? Thanks, Harald PR fortran/95707 - ICE in finish_equivalences, at fortran/trans-common.c:1319 With submodules and equivalence declarations, name mangling may result in long internal symbols overflowing internal buffers. We now check that we do not exceed the enlarged buffer sizes. gcc/fortran/ PR fortran/95707 * gfortran.h (gfc_common_head): Enlarge buffer. * trans-common.c (gfc_sym_mangled_common_id): Enlarge temporary buffers, and add check on length on mangled name to prevent overflow.
