The BackTraceStrFunc by default points to SysBackTraceStr which just converts addresses to strings. If you use -gl then one of the two lineinfo units is included depending on the chosen format of the debug info. This units in turn set BackTraceStrFunc to their own function, so that line and file info is now part of the returned string. So the savest way to ensure that BackTraceStrFunc returns more than just the address us to use -gl.

I use this units to do that. Was someone with the nickname crhonos who made.
