gdb debugging

[Perry Smith]

In my experience with dbx and IBM's xlc compiler, you have to turn off 
optimization to get anything useful from dbx.

Is the same true with gdb and gcc?  Do I need to recompile at least 
part of gnucash without optimization?  I'm looking at the stack trace 
in the middle of the database save and some things look o.k. but a lot 
of things look pretty trashed out.

Thanks,
Perry
