--- Comment #18 from Dodji Seketeli <dodji at gcc dot gnu.org> 2012-10-10 10:25:13 UTC --- Author: dodji Date: Wed Oct 10 10:25:03 2012 New Revision: 192301 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=192301 Log: PR middle-end/54860 - Make sure attributes hash table is created On targets cris-elf, alpha and sparc (for instance) it can happen that the attribute_tables variable is empty for fortran. Thus register_scoped_attributes (called by init_attributes) won't call register_scoped_attributes, so the hash table member of scoped_attributes is not created. Later when we try to e.g, lookup an attribute by calling lookup_scoped_attribute_spec, that NULL member hash table comes to byte us as htab_find_with_hash crashes. This patch fixes this by ensuring in register_scoped_attributes that the hash table is created. Tested on cris-elf, x86_64-unknown-linux-gnu against trunk and some commenters on the bug bootstrapped it on alpha and sparc. gcc/ * attribs.c (register_scoped_attributes): Ensure the attribute hash table is created. Modified: trunk/gcc/ChangeLog trunk/gcc/attribs.c
