I get the following ICE with -gstabs with gcc 4.1.2 20060901 (Debian 4.1.1-13)
but not with 4.0 and 4.2.

This works on 4.1.2 20061007 on i686-linux-gnu.

Fails for me with gcc 4.1.2 20061011 on x86_64-unknown-linux-gnu.  From the
Debian build logs it seems the ICE only appeared on x86_64.

This is TLS that is being ICEd on so I doubt this is a regression, except for
libstdc++ using TLS now.

Sorry, not TLS but instead some PIC code.  This is a target specific issue.
