  Hum, why didn't you use xmlParserInputBufferCreateMem ? 
My take on this is that xmlIOParseDTD frees the parser context
before returning and this includes the input buffer.

I was doing. It makes no difference which you use.

  Maybe the leak is not due to the fact that xmlFreeParserInputBuffer
is missing (I think it's done internally).

I'm not saying there definitely is a leak without
xmlFreeParserInputBuffer, because I haven't tested it. But since the
buffer is malloc'd in xmlAllocParserInputBuffer(), it needs to be freed
somehow, and every way I try causes a segfault, either immediately, or
later on down the line.
