I'm developing a little game using ocaml and lablgtk2. During the game
(under cygwin), I've got a segmentation fault for ocamlrun :

Is there a way to know if the problem comes from ocamlrun or if it comes

Hi, Do you have a backtrace? You could run your application under gdb and use its "backtrace" function to get one. It should show quite quickly whether the issue is from lablgtk, gtk or something else.

Although the message told me I've a core dumped, I have no core: I only have a stack trace.
It's the first time I use gdb. However, I found how to run my program into gdb. It produced the
same kind of error. Here, I could have more information :

So, it seems cygwin is in trouble with my program... Damn !

OutputDebugStringA means there should be some useful info.
Run it under windbg to see the message.
Also look into system event logs.

I tried to look after system logs, but I found nothing about this event.
I looked into Application and System logs of Windows, but I found nothing.

I also tried to run my program under windbg. With my first run (command GN
twice), I could see my program running and then stop with the same kind of error
(STATUS_ACCESS_VIOLATION).
However, I don't understand anything of what windbg told me :
