(The fact that it's SIGBUS rather than SIGSEGV may be because this is
2.6.18, a vserver kernel, on Sparc64 hardware; honestly I'm not sure.)

If I can provide any other information, feel free to ask.
Thanks for your time.

Thanks for checking. It seems gcc does something wrong on sparc 
with -DFORTIFY_SOURCE.

2.2.9-1 was also compiled without -DFORTIFY_SOURCE, like 2.2.8-3. I 
will therefore mark the bug as closed in 2.2.9-1. When you upgrade to 
that version and the problem reappears, please tell me / reopen the 
bug.

Thanks for your help.

Cheers,
Stefan
