[Bug c/38528] New: ICE while building libgfortran (gcc bootstrap)

["bernard at brenda-arkle dot me dot uk" <gcc-bugzilla at gcc dot gnu dot org>]

Apologies if 4.3.3 isn't the right magic version: seen in Revision 142751
(today's live trunk).

While trying to verify Bug 37865 (not connected) on the live tree:
during the building of libgfortran in stage 3 (so supposedly with a
"correct" gcc build) I got

internal compiler error: in change_decl_assembler_name, at cgraph.c:1256

A slightly reduced test-case uses the command-line

/mnt/devel/lfs/lfs-build/gcc-2008-12-14/build-gcc-2008-12-14/./gcc/xgcc
-B/mnt/devel/lfs/lfs-build/gcc-2008-12-14/build-gcc-2008-12-14/./gcc/
-B/usr/i686-pc-linux-gnu/bin/ -B/usr/i686-pc-linux-gnu/lib/ -std=gnu99
-fcx-fortran-rules -march=athlon64 -c error.cpp.c fpu.cpp.c -combine

with the source files attached.   This build was configured as

'../gcc-2008-12-14/configure' '--prefix=/usr' '--libexecdir=/usr/lib'
'--infodir=/usr/share/info' '--mandir=/usr/share/man' '--enable-libada'
'--enable-libssp' '--disable-werror' '--with-mpfr=/usr' '--with-gmp=/usr'

'--with-local-prefix=/usr' '--with-gnu-ld' '--with-demangler-in-ld'

The CPU is an Athlon64 X2.
