I think the problem is bad design of MPFR, not a bug in MPC. GCC uses

The AIX systems to which I have access also are AIX 5.3.0.0 TL 07.
My GCC configure command only specifies the languages and where to find GMP and
MRPF. I had been using gmp-4.1.4 static archive library, but recently

I bootstrap GCC using GCC 4.1. I assume you use GCC 4.2 distributed by IBM.
I do not understand your comment in the initial report about forward porting
of the 4.2.0 patches.

No, I do not use any patches from IBM. The patches seem to be focussed on
packaging and layout, but I would recommend using the standard FSF GCC 4.3.2
release plus the pt.c patch that now is upstream in the FSF GCC

I have not tried MPFR as a shared library.
One thing to be careful about with shared libraries on AIX is libpath. libtool
configured for gmp and mpfr decides to hardcode the path and finds all of the
GCC build

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
--- Comment #17 from dje at gcc dot gnu dot org 2008-09-14 19:52 ---
Because the problem is due to garbage collection, it is non-deterministic,
depending on what data GCC generates. I was able to reproduce the problem in a
recent development version of GCC, prior to Honza's patch
--- Comment #19 from dje at gcc dot gnu dot org 2008-09-14 22:42 ---
First, you reported seven ICEs. You attached files for
makeChemkinReactions.ii. That file failed before Honza's patch and does not
appear to fail after his patch. I cannot reproduce the failure using my
version
--- Comment #7 from dje at gcc dot gnu dot org 2008-09-14 01:22 ---
This is a garbage collection bug.
