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

[bernard at brenda-arkle dot me dot uk]

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-datarootdir=/usr/share' '--with-docdir=/usr/share/gcc-2008-12-14/doc'
'--with-pdfdir=/usr/share/gcc-2008-12-14/doc'
'--with-htmldir=/usr/share/gcc-2008-12-14/doc/html' '--disable-coverage'
'--enable-nls' '--enable-__cxa_atexit' '--enable-decimal-float'
'--disable-fixed-point' '--enable-threads=posix' '--enable-clocale=gnu'

'--with-local-prefix=/usr' '--with-gnu-ld' '--with-demangler-in-ld'
'--with-gnu-as' '--with-system-libunwind' '--with-system-zlib'
'--enable-bootstrap'

The CPU is an Athlon64 X2.

-combine should go away and the code which supports should be removed really. 
It is always broken and will most likely will always be broken.

Is that official?  Do you want to maintain a list of documented gcc
options which unlikely ever to work, for the benefit of the rest of
us?
