To reproduce save attached documents, open MailMerge2.sxw and edit the
pathes appropriately then start the macro from within the Basic IDE.
(Since the stacks were obtained from 7 successive calls it may be nececessary to
start the macro more than once if per chance the respective code is not always
called.)

Setting the target.
Comment 6 mikhail.voytenko 2006-07-17 16:56:45 UTC 
Changing the target.
Comment 7 mikhail.voytenko 2006-11-01 14:42:51 UTC 
For each "inflateInit2()" there is always "inflateEnd()" call, that is called in
the destructor of the Inflater class. So currently the only possibility of the
memory leak seem to be a problem in the zLib library.
Comment 8 mikhail.voytenko 2006-11-01 14:46:04 UTC 
Changing the summary accordingly.
