Do you use the FFI and don't use -O or -fvia-C? There were some
problems with the native code generator on SPARC, which have been
fixed in 5.04.1. So as a rule of thumb, try using -O or -fvia-C on
SPARC if you're experiencing segfaults or the like. Another source of
trouble is GCC 3.x on SPARC, but I've lost track in this area. SimonM?

Anyway, a program demonstrating the bug would be helpful.
