Broken
: Search converges between 2003-04-22-trunk (#236) and 2003-05-04-trunk (#237).

Changed ICE, also ICEd all the time even without -g -frepo:
: Search converges between 2004-07-29-trunk (#498) and 2004-07-30-trunk (#499).

And then fixed fully:
: Search converges between 2004-08-24-trunk (#523) and 2004-08-25-trunk (#524).

It looks like it was fixed on mainline by this patch from mmitchel:

  http://gcc.gnu.org/ml/gcc-cvs/2004-08/msg01218.html

It's hard to be sure because there are build failures at that time for
powerpc-linux.

Do you believe your patch is also good for GCC-3.4.x?
