[AL] Memory Leaks in Allegro

[Oli N. <no...@bt...>]

Hi,

I have created a game in Allegro and have been told that it has some memory
leaks. I understand that for this to happen you would be using the 'new' and
'delete' operators and then forgetting to 'delete' something that you have
created with 'new'. I have searched through my project and have not used
'new' or 'delete' anywhere. I was then thinking the memory leak must be
something to do with Allegro?.

The friend who reported the problem is using Windows 2000 and said the
memory was leaking at a constant rate whilst my program was sitting idle.

I am using Windows 98 with MSVC6 and Allegro 3936. After running my game for
a long time it slows my machine down to a crawl when exiting. I think this
could be the same problem?.

The only thing I can think of that might be odd is that I am loading a new
'background' PCX file (800x600x8) at regular intervals and its when you race
through the game and load the PCX files at great speed the problems occur (I
think).

Basically I have two 'buffers' like this.

BITMAP* buffer;
BITMAP* picbuffer;

I then create them like this.

buffer=create_bitmap(800x600);
picbuffer=create_bitmap(800x600);

And each time I want to get a new picture I do this.

picbuffer=load_pcx("picturehere.pcx",pal);

and then blit the picbuffer onto the buffer when its needed.


I was wondering whether doing this could cause problems and possibly be the
cause of the memory leak?

Also does Allegro 3937 fix anything big with the MSCV port?. I am too scared
to upgrade when I need to have finished my game in the next few days.

Thanks in advance,
