UPD: Tried bootstrapping of GCC 4.6.1. It doesn't fail under such error.

Tried with gcc-v4.7-20110702, now adding `--enable-stage1-languages=c,fortran'
to configure options.
Stage1 builds fine (now stage0 compiler is 4.6.1-release), even with fortran
enabled. On stage2, the process stops at the same moment as I reported
initially.
~/build-farm/_gcc_bootstrap # ls -l prev-gcc/fortran/resolve.o
-rw-r--r-- 1 root 0 455536 Jul 9 00:15
prev-gcc/fortran/resolve.o
~/build-farm/_gcc_bootstrap # ls -l gcc/fortran/resolve.o
ls: gcc/fortran/resolve.o: No such file or directory
I also compared sizes of cprop.o object files on both stages, they do differ
very much (files are also uploaded to
http://ftp.osuosl.org/pub/manulix/logs+errors/gcc-v4.7-20110702/ ):
~/build-farm # ls -l stage*-cprop.o
-rw-r--r-- 1 root 0 959512 Jul 9 10:59 stage1-cprop.o
-rw-r--r-- 1 root 0 314088 Jul 9 10:58 stage2-cprop.o
I also figured out that gcc/cprop.c file does not exist in GCC < 4.7 source
tarballs.
So the possible reason for the error may be Steven Bosscher's efforts to split
gcse.c --> cprop.c and then "clean it up", which caused this regression.
I would be thankful for any response.

I can reproduce this with a cross compiler, I am reducing the testcase right
now.

int next;
}
gfc_actual_arglist;
update_arglist_pass (gfc_actual_arglist* lst, int po, unsigned argpos,
const char *name)
