Summary: Access violation in test.c
Initial Comment:
Allegro 4.2.1, msvc6. The same thing happens with 4.3.0, compiled with minGW.
To reproduce:
1. Start with autodetect windowed, 800x600, 32b.
2. Run Profile Screen.
The second time the vline benchmark starts, it exits with an access violation. No message is shown.
Here's a traceback etc. from windbg 6.

I forgot to mention that this bug only appears in windowed mode. If you
do the exact same thing, except in fullscreen mode, there's no problem.
