Strange Bootstrap Failure

[David Ronis]

Today's CVS gave me the following build failure (make boostrap):

What's strange is that when I ran the command from the command line
(with -save-temps to get intermediate files for a bug report) it
worked; I got the same warnings but no ICE.  I'm running linux-2.2.10
on an i586.  I reran, checking memory usage, and never exceeded 20% of
RAM.  In addition, the machine was fairly inactive during the bootstrap.

1.  Any idea what's going on? 

2.  Is there some way to continue with the bootstrap from this point onwards?
