simutrans r2020 GDI,SDL_Windows

When I loading specific height map, simutrans crash.
This problem happened with self compiled version, nighly SDL and nightly GDI.

This specific file is "Japan.zip" on http://japanese.simutrans.com/index.php?%A5%DE%A5%C3%A5%D7 .
But I don't know you can reproduce this problem or not.

In r2022.
It still causes to crash at the same line.

EDIT:
When I change code like below, crash problem had been solved.
 (Strangely enough, linux versions of r2022 don't crash. )

simworld.cc:786
