  Sorry, I'm a bit under pressure too ...

  if (!abort)
      htmlParseChunk(ctxt, buf, 0, 1);

  I was wrong, I read your code and misunderstood it
I read it as if your SAX handler was identical to the default one but
with just endElement changed, and made a wrong analysis.

  It's clear that there is yet another subtle bug in the push code,
check first that 
   if (!abort)
       htmlParseChunk(ctxt, buf, 0, 1);
is a workaround to your problem.
