hello
can anyone tell me what exactly the following means that occurs during segmentation fault.
Unhandled dwarf expression opcode 0x93
any advice appreciated,
Edit : Its on solaris 10 i386

A:
This may not immediately help, but "dwarf" probably refers to the DWARF Debugging Standard.
The wikipedia entry for DWARF indicates that the file format contains "byte-coded instructions for simple, special-purpose finite state machines". This may mean that you have a corrupted debug info file of some kind, but without more information I wouldn't be able to guess further.

thanks.

Sorry, I don't have enough familiarity with Solaris to guess what those messages mean.
