I would suggest recompiling after applying all of the bug fixes if you
haven't already. This may be an issue that was fixed already. If you patch
amber10 and recompile (don't forget to make clean before trying to
recompile) and the issue remains, it may be worth running through a debugger
(i.e. compile with -g and use gdb/idb). divide-by-zero errors are typically
relatively easy to find using debuggers, in my experience.
If none of this helps, the best option would be to create a reproducible
failure that developers can attack, but until the problem can be reproduced
by others, it can't really be addressed by them.
Hope this helps,
Jason
