Do I do that by typing `list *0x080735ac' (that's what the gdb Info file seemed to suggest, unless I misunderstood)? > It's not clear what code caused the > segfault, and in an optimized build one cannot trust line numbers > reported by the debugger in a backtrace.

Unfortunately, the crash happened late last night and I had to shut down the machine afterwards. But if it happens again, I will try to provide the information you're requesting. Sorry I can't now. :-( Steve Berman
