It's crashing inside libxml2. htmlDoRead calls xmlFreeParserCtxt, which calls
xmlFreeInputStream on a loop:
while ((input = inputPop(ctxt)) != NULL) { /* Non consuming */
xmlFreeInputStream(input);
And then crashes on xmlFreeInputStream in:
if (input->buf != NULL)
xmlFreeParserInputBuffer(input->buf);
Or that's the line gdb points to, but looking at the stack it doesn't seem to
have entered xmlFreeParserInputBuffer, and the function has dereferenced input
many times before that, so I dunno what's going on. Maybe my gdb foo is way bad
:(
Maybe go to frame #14 and check the feed name. Maybe it's always crashing on the
same one.
Cheers,
Emilio
