Thanks to that patch I could get a full stack trace[*], find the cause 
of the exception and correct my error.
Any reason why it hasn't been applied to fpc yet?

[*]addresses only, in spite of the executable having full debug and line 
number information[**], but I could feed those addresses to gdb to get 
the corresponding line numbers.

[**] If I try to dump the stack not in the exception handler (i.e, 
http://wiki.freepascal.org/Logging_exceptions#Dump_current_call_stack), 
BackTraceStrFunc correctly shows the line info, not so during the exception.

Bye
