Crashes in Silver Seed Maze

[Mikser]

I seem to be suffering constant crashes in the Silver Seed Maze (the one with walls that appear/disappear and the cat creature), particularly in the second and third levels.

Contents of stderr.txt are as follows:

Assertion failed: (cx >= 0) && (cx = 0) && (cy < c_num_chunks), file gamemap.h, line 97

Stdout.txt doesn't seem to report anything abnormal, but I'll copy-paste it too if someone asks.

Running most recent snapshot
(=dated 2003-08-27, with changelog entry
* gamemap.cc: enable WANT_MAP_CACHE_OUT permanently)
of Exult 1.1.2 beta. System is Win98SE; I'm using the Scale2X scaler and DigitalMusic options, and I'm obviously running Serpent Isle with Silver Seed.

Also, I suffered numerous crashes in the Mountains of Freedom under an earlier build (one or two snapshots back), but I didn't think to record the contents of stderr.txt back then.

I've been having a similar problem. Specifically, the game keeps crashing when I enter the teleporters in the maze. Stderr.txt only reports this:

Fatal signal: Segmentation Fault (SDL Parachute Deployed).

I managed to avoid this by disabling all the extra graphic effects and setting scaling to point.
