The crash happens at config/i386/i386.c's ix86_init_tm_builtins:

  decl = builtin_decl_explicit (BUILT_IN_TM_LOAD_1);
  attrs_load = DECL_ATTRIBUTES (decl);

The problem is that builtin_decl_explicit returns NULL - or in other words:
   builtin_info.decl[(size_t) BUILT_IN_TM_LOAD_1]
is NULL.

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/*.

Ideas?
