This has been bugging me for some time now. I can find only one other person reporting the problem (it happened to him only once). I've read all about setting the heap_chunk thing in the registry and tried all that, to no avail.
The problem is seemingly not a complaint about not being able to allocate a certain large amount of memory, but a *zero* amount (how could you ever not be able to allocate zero?). Trying the commands repeatedly ultimately works. Can anyone advise? cygcheck -V cygcheck version 1.32 System Checker for Cygwin Copyright 1998, 1999, 2000, 2001, 2002, 2003 Red Hat, Inc.
