Summary: Segmentation Fault

Initial Comment:
I\'ve been working in a project that uses Allegro 5.03. This uses TTF and image add-ons and sometimes (nondeterministic) I receive segmentation fault on ttf.c file line 658 and xdisplay.c file line 715 . I don\\\\\\\'t know why it is happening ... Is anyone have one tip or material that I can read to solve this? I will have thankfull if someone could help me on it.

Best regards,

Compiler: gcc version 4.5.2 (Ubuntu/Linaro 4.5.2-8ubuntu4)
IDE : CodeBlocks 10.05
SO : Ubuntu Linux 11.04

I commented some lines like

//   ASSERT(ogl_bitmap->fbo_info->fbo_state > FBO_INFO_UNUSED);
//   ASSERT(ogl_bitmap->fbo_info->fbo != 0);
//   ALLEGRO_DEBUG("Deleting FBO: %u\n", ogl_bitmap->fbo_info->fbo);

in ogl_bitmap.c

  // FT_Done_Face(data->face);

in ttf.c

and now my program receive segmentation fault once at the end, on line
XCloseDisplay(sx->x11display); in xsystem.c file..... 

I will continue looking errors in the code for try help to solve it . Best

Hello Elias, Thank you for the answer!
I've uploaded the core dump and some logs generated on terminal using
option -g0 on gcc. With the code from svn is occurring the same errors.

Can you run with the debug version of Allegro and attach the generated

Also, can you get a debugger backtrace?

And lastly, if you can try that, does the same happen with the SVN version
of Allegro?
