A possible memory heap problem

[Duane Clark]

Howdy,

I have an application (schedit) which appears to be having a memory heap 
problem with current CVS. This application has worked very well under 
wine up to mid July or so. Now it generates a lot of these messages and 
just hangs:
err:local:LOCAL_GetBlock Local heap not found
err:region:CombineRgn Invalid rgn=0000

Here is what is happening up to that to first of those messages, 
according to --debugmsg +relay,+local
