Revision: 176 http://trac.macosforge.org/projects/libdispatch/changeset/176 Author: robert@fledge.watson.org Date: 2009-12-28 03:28:23 -0800 (Mon, 28 Dec 2009) Log Message: ----------- Rather than returning NULL from malloc_create_zone and malloc_default_zone, return (void *)-1 on platforms without malloc zone support. Assertions under DISPATCH_DEBUG appear to require a non-NULL result, so provide one but not a pointer that can be used for anything (since that would be a bug). This is slightly different from the submitted patch, which returned a small ammount of malloc'd memory, in that I want to cause a segfault if the returned pointer is ever dereferenced, since that would imply a consumer that knows more about the internals than we implement in our stubs.
