Two thoughts come to mind.  First, qualify your system with a known  
to build, known to be good compiler.  Build it 20 times, if it never  
fails to build, you probably have a good system.  If it ever fails,  
toss the system out and get a real machine.  :-)

If you need help reading a build log, well, this isn't quite the  
right place for it.  Look for '***' in the log as a very rough  
approximation.  Does sound like you did track it down to the right  
failed file.

Ok.

Run the command with the -O2 option, does it fail?  If so, does it  
always fail if you run it 5 times?  If so, that bug is probably a run  
of the mill compiler bug.  Feel free to file a bug report.  Do make  
sure you have enough memory and paging file space on the system though.

Also, you should be able to check the gcc-testresults mailing list, say:

   http://gcc.gnu.org/ml/gcc-testresults/2006-11/msg00519.html

and try and replicate the result.  If you can, then you probably  
don't have to worry about your system.  If you can't...  well, not  
much we can probably do.

If you can't find any results to compare to, you might want to use  
cygwin and compare against, say

     http://gcc.gnu.org/ml/gcc-testresults/2007-02/msg00886.html
or http://gcc.gnu.org/ml/gcc-testresults/2007-01/msg00811.html
