[Gambas-user] Debugging Gambas

[T Lee Davidson]

This reminds me of a recent thread in which it was mentioned, paraphrased, that it seems we are expected to guess exactly what 
the user's code is doing.

All I can suggest is that you look into `gdb`, `strace`, `lsof`, Valgrind, and/or perhaps trying with the latest stable Gambas 
version.
