             Bug #: 50206
           Summary: Internal compiler error in xgcc while trying to
                    bootstrap 4.6.1
    Classification: Unclassified
           Product: gcc
           Version: 4.6.1
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P3
         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: david@thornley.net


I am running Ubuntu 10.04 LTS on an Intel Core 2, and wanted to install a later
version of gcc.  I downloaded gcc-4.6.1-tar.gz on August 25, 2011, opened it
up, and tried to bootstrap.  The source was in directory gcc-4.6.1, and I was
trying to compile in directory gcc-4.6.1-bin.  I executed the following from
that directory:

../gcc-4.6.1/configure --program-prefix=my
ls
make
make bootstrap
make clean
make bootstrap

I got crashes on all makes (except make clean), but am only reporting the last.

There was a lot of output.  I copy-pasted the terminal to file error.txt
(attached) from the command that started the crash to the end of the output.
