[Gambas-user] Bug affecting to ShowModal

[Jussi Lahtinen]

Yes, after I wrote my mail, I figured it may be the case.
Problem is that my program is oriented to module.
It invokes forms when needed and shows with them what
happens inside of module.

Project I'm working on is big, old and messy. It is ported from vb6.
Now I'm trying to make code more clear, but I'm getting signal 11.
I can't send this project to you, but I'm trying to isolate the problem.
Do gdb outputs help you without source code?
However, here:

Program received signal SIGSEGV, Segmentation fault.
my_free (alloc=0x1e1d150a1e1d150a) at ../share/gb_alloc_temp.h:333
333		pool = (size / SIZE_INC) - 1;
(gdb) bt
#0  my_free (alloc=0x1e1d150a1e1d150a) at ../share/gb_alloc_temp.h:333
