Memory leaksOwen, I did a pretty extensive memory leak test with bounds checker about 8 months ago. Since then I have not done one, but am going to do another run through in the next week or so (maybe even this evening), will post my results.

I have had a qwik search through the archives re: leaks but didn't find a great amount of detail, hence my post. Below are 4 stack traces of where I believe there are a few leaks, followed by a modification I made to HTProfile_delete() which cleared up a bunch of other ones I found at the top level. (I made some other minor changes as well which should become obvious if you tried the additional code as below, re crashes when start-terminate multiple times) I saw reference to one of the leaks below in the list I think, the one where a timer is being allocated in HTHost_free() during HTTP cleanup. Does anyone have any further information on reducing/eliminating memory leaks for post 5.3.2 source code? Does the latest in CVS fix any of these?
