Hi Marc,
Thanks for the pointer. Fortunately I don't have this problem. Probably 2GB
of memory are enough to parse 20MB file even with this space leak. HXML
still works better than the other libraries and has a nice API so I use it.
The patch is useful but it is not applied. I also did some other changes in
HXML. It seems like the library is not maintained. Should I package it and
upload to Hackage?
Regards,
Krasimir
