I have spend the morning tracking down a bug that shows up only for a bootstrapped compiler. This is on i686-pc-linux-gnu.
The bug is in libgcc:bid64_add.c The reason that the problem does not show up for the stage1 compile is that libgcc is built without -fomit-frame-pointer in the stage1 build and with -fomit-frame-pointer in the stage3 build. Aside from that the command lines are the same. This seems like a bug. Any comments? stage1 command /gondorpublic/gbG2/./gcc/xgcc -B/gondorpublic/gbG2/./gcc/ -B/usr/local/i686-pc-linux-gnu/bin/ -B/usr/local/i686-pc-linux-gnu/lib/ -isystem /usr/local/i686-pc-linux-gnu/include -isystem /usr/local/i686-pc-linux-gnu/sys-include -O2 -g -O2 -O2 -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fPIC -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -I. -I. -I../.././gcc -I/home/zadeck/gccGlobal/libgcc -I/home/zadeck/gccGlobal/libgcc/. -I/home/zadeck/gccGlobal/libgcc/../gcc -I/home/zadeck/gccGlobal/libgcc/../include -I/home/zadeck/gccGlobal/libgcc/config/libbid -DENABLE_DECIMAL_BID_FORMAT -DHAVE_CC_TLS -DUSE_TLS -o bid64_add.o -MT bid64_add.o -MD -MP -MF bid64_add.dep -c /home/zadeck/gccGlobal/libgcc/config/libbid/bid64_add.c stage3 command /gondorpublic/gbGlobal/./gcc/xgcc -B/gondorpublic/gbGlobal/./gcc/ -B/usr/local/i686-pc-linux-gnu/bin/ -B/usr/local/i686-pc-linux-gnu/lib/ -isystem /usr/local/i686-pc-linux-gnu/include -isystem /usr/local/i686-pc-linux-gnu/sys-include -g -O2 -fomit-frame-pointer -O2 -O2 -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fPIC -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -I. -I. -I../.././gcc -I/home/zadeck/gccGlobal/libgcc -I/home/zadeck/gccGlobal/libgcc/. -I/home/zadeck/gccGlobal/libgcc/../gcc -I/home/zadeck/gccGlobal/libgcc/../include -I/home/zadeck/gccGlobal/libgcc/config/libbid -DENABLE_DECIMAL_BID_FORMAT -DHAVE_CC_TLS -DUSE_TLS -o bid64_add.o -MT bid64_add.o -MD -MP -MF bid64_add.dep -c /home/zadeck/gccGlobal/libgcc/config/libbid/bid64_add.c Kenny
