Subject: Memory leak when parsing HTML documents with errors
Download (untitled) / with headers
text/plain 320b
When investigating bug #79118, I found that XML::LibXML leaks memory when parsing HTML files with errors (if the recover option is *not* set). The HTML parsing code in LibXML.xs should call LibXML_will_die_ctx and destroy the result if it returns true, like the XML parsing code does. See attachment for a test script.
