Description Aleksey Sanin 2004-09-20 17:16:53 UTC 
After parsing a chunk of XML with xmlParseInNodeContext() and then inserting it
into the document, xmlFreeDoc() crashes in tree.c:3326 (example program is
following).

Note that the crash goes away if you do any of the following
1) use XML_PARSE_NODICT flag in xmlParseInNodeContext() function
2) remove the "xsi:type" declaration from the parsed by xmlParseInNodeContext()
function buffer
3) change the node content in the parsed by xmlParseInNodeContext() function
buffer (to avoid crash, the content should *not* be a single character or a
single digital or a serials of blank)

Comment from Daniel: "This sounds like a dictionnary mixup bug..."

test file needed to run test program

This file should be in the same folder as the test program executable

I added coding to force the XML_PARSE_NODICT option if the doc from the context 
node does not have it's own dictionary.  This certainly fixes your test 
program - could you please check whether it solves your original problem, and 
re-open the bug if there is any further trouble?  Changed code is in CVS 
(parser.c).

Works for me now. Thanks! I will ask the original reporter to try it and will
close the bug after that.
Comment 5 Daniel Veillard 2004-10-28 07:24:54 UTC 
This should be fixed in release 2.6.15,

  thanks,

Daniel
