Strange and interesting.
I can replicate this with Therion 6.4.0
How did you deduce that 0.1 degree inclination change should bypass the problem?

Hello
I have error, when using command «color map-fg altitude».
If i had commented survey in Berloga.th — « v78 v79 4.61 172.9 -41.7» or changed vert angle to -41.8, then all compiling ok.
Log of error:
