[Bug c++/37057] 7 Internal Compiler Errors when compiling OpenFOAM-1.5

["dje at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #15 from dje at gcc dot gnu dot org  2008-09-14 15:35 -------
Honza,

I think that your recent pt.c:tsubst_decl() fix coincidentally may have fixed
this as well.  Tracing the ggc_alloc_stat() calls, struct function only appears
to be allocated once, but likely is copied when it should not be.

Jørn,

Could you try rebuilding GCC 4.3.1 with Honza's patch and report if it fixes
your failures?
