Subject: dosbox: doesn't start due to invalid free

Date: Sun, 30 Jul 2006 18:44:42 +0200

Package: dosbox
Version: 0.63-2.2
Severity: important

Hello,

dosbox fails to load because of freeing unallocated
memory, which causes a crash. Also, if run under
valgrind which allows it to continue, it does
not process any keystrokes.

The valgrind output is attached.

Could you try 0.65-1, maybe the problem is fixed there.

There is something wrong with the attachment (It is missing)

This will take time, but I'll try. Nevertheless, I think
the problem may be in SDL, as I encountered similar
problem in other SDL applications too.

> There is something wrong with the attachment (It is missing)

Yes, this IS definitly something wrong :-) It seems to be a
problem in my MUA (Opera on Windows) which seems to ignore
attachments which are on my Linux disk. I apologize. This time,
everything should be OK.

That indeed looks like an SDL problem.
The invalid free seems to be happening the sdl subsystem initalisation.
Should this bug report be transfered to them ?

thanks

Hello,

I have built a debug version of sdl and created a patch. The
problem was that something was allocated from stack, but then freed
to the heap. The patch is attached.

Err, I have posted a wrong patch (reverse). This patch should be better.
