So I do not see the values you printed from GDB below. This is general debugging of GDB, it no longer belongs to this list. You should best file it to GDB Bugzilla and try to provide reproducibility information. There seems to be some 32->64bit extension problem (0x100000000). Isn't the GDB built for x86_64 target while you run it for i386 target? This sure should work but there may be some issues. Try to build 32-bit host GDB as troubleshooting: CFLAGS=-m32 ./configure i386-unknown-linux-gnu But this is already rather for the Bugzilla. Jan
