No, it's not.

I don't yet know about 2.9.8, but the crash with 2.9.4 is a bug in
libxml2's error handling which has _nothing to do_ with which API you
use. Read the analysis I posted.

ok. Probably there are more than one issue. 1. crash, 2. raising huge input lookup, maybe other.

libxml2 is great library, but I didn't understand their system still.

Pavel
