Bug #: 51291
Summary: ICE: SIGSEGV in ix86_init_builtins (i386.c:27691) with
any fortran code
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3

ReportedBy: zsojka@seznam.cz
CC: amacleod@redhat.com

It seems any fotran code triggers this segfault:
Compiler output:
$ echo '' > testcase.f
$ gfortran testcase.f -fgnu-tm

The problem is that gtm-builtins.def is included in builtins.def which is included in c-common.c. However, builtins.def is not included in fortran/*.
