Please do not paper over the problem but fix the application bugs instead.
Compiling it with -g and using gdb on the core should tell you where it
dies.
Thanks,

The error happens inside registerProtocols2 in file wmapp.cc, line 238.
I can't see any problem in the code, and as it works when the compiler optimizations are disabled, I guest it is a gcc bug. Unfortunatelly, I don't have enough knowledge about SPARC assembler and ABI to follow the generated code.
