Summary: Invalid free when using XML SAX parser
Initial Comment:
I'm running a fairly complex script, combination of a few different binaries...
right now this is what i know is happening from valgrind:
==11639== Invalid free() / delete / delete[]
==11639== at 0x4C2433D: free (vg_replace_malloc.c:323)
==11639== by 0xD5AB4CA: xmlFreeParserCtxt (in /usr/lib64/libxml2.so.2.7.3)
==11639== by 0x4E77D51: (within /usr/lib64/libruby.so.1.8.6)
==11639== by 0x4E780E6: ruby_xmalloc (in /usr/lib64/libruby.so.1.8.6)
==11639== by 0xC69C7BE: alloc_hpricot_struct (hpricot_scan.rl:618)
==11639== by 0x4E62E00: (within /usr/lib64/libruby.so.1.8.6)
==11639== by 0x4E62FFC: (within /usr/lib64/libruby.so.1.8.6)
==11639== by 0x4E63D17: (within /usr/lib64/libruby.so.1.8.6)
==11639== by 0x4E63FC4: rb_funcall (in /usr/lib64/libruby.so.1.8.6)
==11639== by 0x4E8E06E: rb_obj_alloc (in /usr/lib64/libruby.so.1.8.6)
==11639== by 0xC69CD13: rb_hpricot_token (hpricot_scan.rl:302)
==11639== by 0xC6A7A20: hpricot_scan (hpricot_scan.rl:68)
==11639== Address 0xd5773a0 is 0 bytes inside data symbol "rxml_sax_handler"
I will work on reducing this to a easier to reproduce test case...

XML is big (> 2GB) but it doesn't seem to have problem with even bigger ones(>
5GB), so I don't think that's the issue,
