Glsl segmentation fault on Azure Coast maps

[sanderd17]

When I open Azure Coast with glsl enabled, I get a segmentation fault, with the following gdb backtrace:

Program received signal SIGSEGV, Segmentation fault.

This doesn't happen on other maps as far as I've seen. But the Azure Coast is one of the biggest maps available.

Playing without glsl enabled will become irritation, as the texture used to visualise the temple aura is only visible with glsl. (just as the waterfalls, but that doesn't matter a lot).
