No it shouldn't. Can you try strace, that should give you the full result code. Also can you try gdb. You can't breakpoint in the wrong-endian region, but it looks like you're getting through that anyway. So try setting a breakpoint at line ~77, and you should be back in BE. Then you can single step and see where it errors out. > BTW, we need to add one .gitignore file to this new test directory. Oh yeah, thanks for the reminder. cheers _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
