Comment 6 for bug 6769

I have been testing this issue further in a unstable chroot (at vore). This
bug reproduces in gcc-2.95, gcc-3.2 and gcc-3.3 in unstable. Running it
through a debugger:

Bench.c (line 100) just does

        signal(SIGALRM, bench_handle_timer);

If the signal call is removed it will not segfault (but will not run
properly either):

Benchmarking: Standard DES [24/32 128K]... Alarm clock

Christian hast said (in IRC) that it seems that the devel branch will not
compile properly on Sparc. I have succesfully tested a built on Solaris
over Sparc, so there seems to be an issue with the linux-specific code. I'm
not sure where the default resides (maybe libc6?). I would suggest that
this bug was reassigned to libc6 and that sparc support for john was
dropped (but this bug left open) until the issue is fixed.
