--- Comment #4 from Mikael Pettersson <mikpe at it dot uu.se> 2011-05-06 11:19:10 UTC --- The smallest .o file that fails bootstrap comparison is libiberty/alloca.o, which get 150 bytes of .text with stage1 xgcc but 148 bytes of text with stage2 and stage3 xgcc (same options). -fcompare-debug doesn't complain. Looks like stage1 miscompiles stage2.
