Let me explain myself. The Makefile distributed with gcc 1.33 uses CFLAGS=-g. I changed this line to CFLAGS=-O. Then I run: make make stage1 make CC=stage1/gcc CFLAGS="-O -Bstage1/" rm -fr stage1 make stage2 make CC=stage2/gcc CFLAGS="-O -Bstage2/" at this point, I get a core dump from stage2/cc1 when compiling "toplev.c". If I repeat this process without the -O, ie, CFLAGS= in the Makefile, and make make stage1 make CC=stage1/gcc CFLAGS=-Bstage1/ rm -fr stage1 make stage2 make CC=stage2/gcc CFLAGS=-Bstage2/ Then I don't get any core dump and the *.o files compare ok with the ones in stage2/*.o My interpretation of this is that the "stage1/gcc -O" phase generates bad code which makes stage2/cc1 core dump on toplev.c.
