1) Could you attach a gdb backtrace of one of those segmentation faults, please? 2) Also, please attach the entire build log to this bug report.
How can I provide a "gdb backtrace"? I can use strace, is it also OK?
OK I see how to do it. You will get the needed info this evening.
It seems it crashes only when using SSH Here is the backtrace: Program received signal SIGSEGV, Segmentation fault. 0xb7ec2fba in svn_txdelta_apply_instructions () from /usr/lib/libsvn_delta-1.so.0 (gdb) backtrace #0 0xb7ec2fba in svn_txdelta_apply_instructions () from /usr/lib/libsvn_delta-1.so.0 #1 0xb7ec352e in ??

What happens if you remove -mtune=generic or replace it with something specific?
This were the flags GCC gave me for "-march=native -mtune=native", for that ATOM N270.
Well, the only suggestions i can give you are to: - check that the gcc on both computers is the same - try something else than mtune=generic Beside that i cant support any distcc setup since i dont have such setup to test myself.

Hello, I changed CFLAGS to "-march=atom -mtune=atom", but it still segfaults if it is cross-distcc'ed.
Since this report is about a version removed from the tree for a long time, i will close this bug as obsolete. Please open a new bug, if you can reproduce it with a current version.
