Good news: I'm able to reproduce this both with the selected patches in
2.0.3-3 and the current upstream SVN snapshot.

Core was generated by `/usr/sbin/apache2 -d /home/buildd/mod-perl2/ModPerl-Registry/t -f /home/buildd/'.
Program terminated with signal 10, Bus error.

It would seem that the SIGBUS is an unaligned access caused by the U32 ->
U16 changes in upstream r615751. I'll rebuild libperl with -g -O0 next
so upstream can look at it better, but that's going to take a while
because my sparc box is quite slow...

Cheers,
