Summary

0004651: crash at exit in ShaderHandler.cpp:51 after shader compile failed

Description

sidenote: its the LoadMap branch, but very likely happens in develop branch as well.

also ForceShader = 1

i'm using the opensource drivers which seems to work quiet well. imo its close before shaders could be enabled as default for it.

Steps To Reproduce

get some shader to fail compile, exit -> crash

Notes
~0013931 Kloot (developer) 2015-01-20 13:46	can't reproduce (with regular nvidia driver blob)

~0013934 abma (administrator) 2015-01-20 23:51	i hope the fix is correct? https://github.com/spring/spring/commit/a2951703eea53fc94c45db630532b704f6fb0a76 for me it works...
