Final Fantasy IV : The complete collection

System: Ubuntu 13.10, AMD64, using libsdl1.2-dev 1.2.15-5ubuntu2
Versions tested (same behavior in both):
v0.9.5-213-g2fe898c (angelXwind build)
Nov 23rd Github master @ 132fe47c7d

I am getting a segfault at Mist village when Rydia first summons Titan. I've discovered that enabling Low Quality Spline/Bezier Curves fixes the issue (I saw TesselateBezierPatch() in the backtrace).

I am posting this here in hopes it will be useful to the developers or anyone else seeing this problem... I can provide save/state files if needed, but it seems to be pretty easy to reproduce.

Output was:
