[Gambas-user] Gambas error messages

[Jussi Lahtinen]

Or here is something you could do:

gdb gbr3
set args /usr/local/bin/gambas3 (or what ever is your install path)
run

You may need to kill the process with Ctrl + c in debugger.
Then with bt, you will get backtrace.
Send it here, so we can see what is happening.
