Unhandled dwarf expression

Question

Can anybody tell me what exactly the following segmentation fault means?

Unhandled dwarf expression opcode 0x93

Its on solaris 10 i386.

Answer 1

This sort of error message ("unhandled dwarf expression") can occur if your version of GDB is too old (older than the compiler that generated the code). Try installing the latest version of gdb and running that.

Answer 2

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.
