| Primitives addon shutdown code shutting down d3d? |

I'm not sure what I'm doing wrong. It's probably my fault but my program is crashing in al_shutdown_primitives_addon, called from al_uninstall_system, called from atexit. I'm using a very recent git build, with MinGW 4.8.1 and Vista. Here's the backtrace : 1Program received signal SIGSEGV, Segmentation fault.
20x00402de0 in AssertHandler (exp=0x678671b0 <__func__.6213+193> "display", file=0x678671b8 <__func__.6213+201> "C:\\mingw\\LIBS\\A5GIT\\allegro\\src\\display.c", line=310, func=0x678673fd <__func__.35368> "al_get_display_flags") at C:\Research\RawInput\InputTest\MouseTestMain.cpp:12

For some reason the display is null at the point when al_get_display_flags is called. However, this begs the question, why is the primitives shutdown code shutting down d3d?

Edgar Reynaldo said: However, this begs the question, why is the primitives shutdown code shutting down d3d? It's not, it's just shutting down the D3D driver of the primitives addon. Is this something easily reproducible? "For in much wisdom is much grief: and he that increases knowledge increases sorrow."-Ecclesiastes 1:18 |

No, I can't reproduce it anymore. Now my program is crashing somewhere else, but only in release mode. If I link to the debugging allegro monolith it doesn't crash. I can give you the backtrace, but there are no line numbers. However, it crashes while trying to create an opengl display. 1Program received signal SIGSEGV, Segmentation fault.

I should say, just out of chance, I have created both a main D3D display, and each mouse pointer opens an OpenGL display (which takes way longer, and now crashes for some reason).

I suspect uninitialized variable/memory access. -- |
