Any idea about this situation? Do you mean 'make' ended up with error and compiling libgcc2.c alone comes to no problem ? How do you perform debugging ? The easiest way I know is 1- make 2- select the last compilation (the one which provokes error) 3-run gdb --arg [last compilation] Here is a cancrete example: /home/guest1/gcc/build_target/./gcc/xgcc -B/home/guest1/gcc/build_target/./gcc/ -B/home/guest1/target/target/bin/ -B/home/guest1/target/target/lib/ -isystem /home/guest1/target/target/include -isystem /home/guest1/target/target/sys-include -O2 -g -g -O2 -O2 -O2 -g -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -g -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc -I. -I. -I../.././gcc -I../../../gcc-4.3.3/libgcc -I../../../gcc-4.3.3/libgcc/. -I../../../gcc-4.3.3/libgcc/../gcc -I../../../gcc-4.3.3/libgcc/../include -o _muldi3.o -MT _muldi3.o -MD -MP -MF _muldi3.dep -DL_muldi3 -c ../../../gcc-4.3.3/libgcc/../gcc/libgcc2.c \ xgcc: Internal error: Segmentation fault (program cc1) Please submit a full bug report.
