With the CVS as of D2004.03.26.12.00.00 (i.e., GTY markers on the reg_known_value array), GCC bootstraps with --enable-languages=c. I'm now doing a full bootstrap. I looked at the compilation that was failing with gdb. However, due to changes in memory consumption, garbage collection no longer occurs while in loop_optimize. I guess that Richard's patch would have to be back ported to D2004.03.18.16.43.00 to be absolutely certain whether it fixes the problem. Dave -- J.
