[Bug bootstrap/14671] [3.5 regression] caller-save.c:491: internal compiler error: Segmentation fault

[danglin at gcc dot gnu dot org]

The segfault is caused by the poisoning of reg_known_value[294].  It is
initially set to a reasonable rtx in init_alias_analysis.  However, the
garbage collector is now run between optimization of loops
(PR optimization/12440) and this somehow poisons reg_known_value[294].
