[Gambas-user] 1.9.2 IDE causes SEGV when FMain is saved

Fri Jan 28 16:48:00 CET 2005

If I do the following in a copy of the IDE, gbx2 will segv.  I 
have attached gdb output including what appears to be a useless 
backtrace.

1. Start gambas2 (whether as "gambas2" or as "gbx -x 
/usr/bin/gambas2")
2. Open a copy of the IDE
3. Open form FMain
4. Mark FMain as dirty, e.g. by moving it
5. Press Control-S to save the form

Boom, segmentation fault, gambas2 goes away.  FMain.form is also 
gone, having already been renamed to FMain.form~.  The location 
of the crash in gbx2 appears to be:

EXEC_enter () at gbx_exec.c:291
291       func = &class->load->func[EXEC.index];

Vanilla build of Gambas2 1.9.2 from my own RPMs under Mandrake 
10.1.
