If you can not use any debugger, then the only way is lots of writeln 
(or LCLProc.Debugln) and DumpStack...

If it is just you can't use Lazarus to debug => you can still use gdb 
itself (Lazarus uses gdb too)

For example, if you code is executed in a http-server, gdb can "attach" 
to the already running server (Lazarus does not yet support that)

Another way is, if you cant debug your code on the life system, write a 
test case. A stand-alone app, that uses the units, and calls the code in 
question with simulated data. Then debug the test case
