Gas hanging

[Todd Squires]

Dear GNU assembler author,

Today, after compiling gcc 2.95.2, I noticed that the
version of gas I am running:

/usr/local/bin/as --version
GNU assembler 2.9.1
Copyright 1997 Free Software Foundation, Inc.
This program is free software; you may redistribute it under the terms of
the GNU General Public License.  This program has absolutely no warranty.
This assembler was configured for a target of `alphaev56-unknown-linux-gnu'.

could be made to hang while attempting to assemble output from the new
compiler.

So far, this has only occurred on one particular file, but it happens
reliably on this file. 

After a visit to gnu.org, I looked around, and saw no new version of
binutils. So, I picked up the source for 2.9.1, and rebuilt it (using
the new compiler) (and the existing 2.9.1 assembler which thankfully
did not hang during the build). Unfortunately, the assembler resulting
from this build also hangs when assembling this particular file.

Here are the details:

Host machine is a DEC Alpha LX164 (ev56) 320MB RAM running Linux 2.2.14

uname -a
Linux oberon.ct0.com 2.2.14 #3 Tue Oct 3 14:50:26 CDT 2000 alpha unknown

cat config.status
#!/bin/sh
# This file was generated automatically by configure.  Do not edit.
# This directory was configured as follows:
./configure --host=alphaev56-unknown-linux-gnu --norecursion 
#  using "mt-frag"

command line which shows the problem:
/usr/local/bin/as pseudo.s
<hang>

The file "pseudo.s" is reasonably large (70K) so I placed it on
my ftp site instead of enclosing it here:

ftp://ftp.ct0.com/pub/pseudo.s

I messed around a bit and located the particular line of the file
which is causing problems. It is marked with comments which contain
many @@@@ characters, so they should be easy to find.

Let me know if you have difficulty reproducing this problem, as I can
arrange to give you ssh2 access to the machine which is exhibiting it.

Thanks in advance for your efforts,
