Ummm... uh... the following says it all:
Release LPRng 3.6.20 - Sun Jun 25 16:34:15 PDT 2000
One of the silly memory leaks that has been reported, tested for,
analyzed, etc., finally was found. The problem was in the
child.c file, where I keep track of children processes
by dynamically allocating a list. While I carefully cleaned
up the list in children of the main LPD process,
I never cleaned up the list in the main LPD process. Thus,
if you created a large number of children the list would grow
a small amount (4 bytes) for each child.
This problem was found by brutally using the 'DMALLOC' debugging
package, finding every 'malloc' call in the main LPD process
and then looking for a matching free call in the main line loop.
When one was not found for the case where I had 0 processes
I knew that I had found the problem. Sigh.
(Stumbled over after staring at the code for a week by:
Patrick Powell <[EMAIL PROTECTED]>)
The call to 'Remove_tempfile()' routine was removed from
the 'cleanup()' when trying to find the above mentioned memory
leak and was not put back. Bad Coder! Bad!
