Confirmed. Janus - I think it could be do to your 4.5 argument checking
patches.
==8885== Invalid read of size 8
==8885== at 0x4C2050: compare_type_rank (interface.c:474)
==8885== by 0x4C20C4: generic_correspondence (interface.c:905)
==8885== by 0x4C28B9: gfc_compare_interfaces (interface.c:986)
==8885== Address 0x98 is not stack'd, malloc'd or (recently) free'd
At a glance, the code looks innocent. interface.c:474 is the last line of:
compare_type_rank (gfc_symbol *s1, gfc_symbol *s2)
{
int r1, r2;
r1 = (s1->as != NULL) ? s1->as->rank : 0;
r2 = (s2->as != NULL) ? s2->as->rank : 0;
The call is:
if (f2 != NULL && compare_type_rank (f1->sym, f2->sym))
Seemingly f2->sym is NULL.
