Bug#651934: How to debug seed FTBFS on sparc?

[peter green]

seed currently FTBFS on sparc with a bus error.

I've reproduced this on a sparc box that Tom Theisen made available 
(thanks tom) but i'm kinda stuck on how to debug it.

Any ideas on how to debug this? Normally i'd start by turning down the 
optimisation but this package doesn't seem to be using any in the first 
place. I tried to use gdb but ran into issues with the libtool wrapper 
scripts.
