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

From stackoverflow

• 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.

• hello, thanks for reply. this is available from gdb. mentioned debug related info. never seen a trace like this so will need to read the material you pointed at. does the info below suggest anything useful??

  thanks.
