[xml] Crash when parsing bad HTML


I'm using the HTML parser (htmlParseDocument) and my application segfaults when processing this document:

  Some text

The gdb traceback is:
#0  0x0000002a96e3a4e4 in xmlSAX2ProcessingInstruction () from /usr/lib64/libxml2.so.2
#1  0x0000002a96db9779 in htmlParseEntityRef () from /usr/lib64/libxml2.so.2
#2  0x0000002a96dbb69a in htmlParseElement () from /usr/lib64/libxml2.so.2
# ...

Of course, it's bad HTML but an exception would be more acceptable. I tried using the latest official version (2.6.29) and the problem occurs there too. Is there a patch somewhere? If not, a hint would be appreciated because I'm going to have to fix it.

Cheers, Pierre
