Re: [xml] xmlDocDumpMemory problem under Windows

[Gary Pennington <Gary Pennington uk sun com>]

What is this, the memory debug mailing list?

You don't say which version of libxml, but since the problem is only
manifested on Windows I'll take a guess that the problem is related to
the fact that you should use xmlFree not free. I know that on Unixen,
the xmlFree function just maps directly to free, I've no idea what
happens on Windows but it may not be so straightforward (for instance
HeapAlloc/HeapFree may be used).
