It looks like the cc1 compiler is miscompiled.  Which stage of the bootstrap is
this?  Could you post a backtrace of cc1 from within gdb when it executes the
illegal instruction?  Is that a recent problem on the 4.5 branch?

Thanks, Eric.  I do not have access to a such a system but will try to
get a backtrace.

A log showing the problem (though not from this very build) is at:
http://pointyhat.freebsd.org/errorlogs/sparc64-errorlogs/e.8.20100704113633/gcc-4.5.1.20100624.log.bz2
and logs in general can be found at
http://portsmon.freebsd.org/portoverview.py?portname=gcc45

The build fails as follows, so we're in stage 2:

gmake[2]: *** [configure-stage2-target-libgcc] Error 1
gmake[2]: Leaving directory `/work/a/ports/lang/gcc45/work/build'
gmake[1]: *** [stage2-bubble] Error 2
gmake[1]: Leaving directory `/work/a/ports/lang/gcc45/work/build'
gmake: *** [bootstrap-lean] Error 2
*** Error code 1

I don't think this problem is very recent on the GCC 4.5 branch; it
does not seem to occur with GCC 4.4., though.

Gerald, we have problems with the third-party libraries (GMP,MPFR,MPC) on the
SPARC, newer versions are miscompiled by earlier versions of GCC.  So I'd
suggest to stick to the minimal versions listed in:
  http://gcc.gnu.org/install/prerequisites.html
