MJ2: realloc is misused and may leak memory #168

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
One shall never write
   p = realloc(p, len);

but 
   p2 = realloc(p, len);
   if (!p2) { handle the error/free the memory/...}

Most calls to realloc have been fixed in r1896.

Somebody should have a look at libopenjpeg/t2.c, I'm not sure whether bio shall 
be destroyed or left alone at 3 lines in t2_decode_packet().

luc the code base changed quite a lot, I cannot find the realloc call you are 
talking about. I am closing the issue for now, please re-open if you can find 
it in current openjpeg codebase.

Indeed, I had a quick look to the current code base. I've just found a few 
remaining misuses in openmj2/j2k.c.
