[Bug gas/879] New: gas fails to assemble valid code

[jneuheisel at gmail dot com]

I am using the latest CVS HEAD version of the gcc 3.4.4 branch, as well as the
CVS HEAD version of binutils.

gcc failed to compile the process.c file in the 2.6.11.7 version of the Linux
kernel.  It turns out that gcc was able to produce valid assembly code, but gas
was not able to create an object file.

I asked gcc to produce an assembly file called capture.s.  I then tried to use
gas to create the object file.

Note that the earlier version of gas was able to produce the object file without
error.

The file capture.s is quite long, so I'll put it on my webserver for a while
instead of pasting it in this report:

If I can furnish any additional information that would be useful, please let me
know.
