GDB and Lazarus (well, fpc) sometimes does not agree about the line to
be shown, sometimes the debugged line is one line below so you are
watching in Lazarus the previously executed line.

This effect seems to be some kind of misunderstood between fpc debug
info and gdb (gdb 7.0 seems to be more precise in this field) but I
was unable to find the gilty of such behavior.

This could also happend when you do not full recompile the code and
debug an ".inc" file, as this file may had not been recompiled at all
because the ".pas" one was not modified.

Check the "debugger output window" for the returned line number on
each step, you'll find it at the end of the last line.
