[Gambas-user] ARM debugging - where to start?

Gambas 2 already runs some project on ARM, but two ARM computers are well-
known to be very different!

Go to the directory of the Gambas 2 project you want to run, and use the 
debugger. Hit CTRL+C to stop it when it loops, and send me the backtrace.

$ cd /path/to/my/gambas/project
$ gdb gbx2
...
(gdb) run
...
^C
(gdb) bt
...

Please try to compile the latest version of gambas, and with debugging 
information enabled. Try to compile with and without optimization too, to see 
if something changes.

Regards,
