[fixed]COpenGLSLMaterialRenderer::linkProgram heap error

[xDan]

Hi, I get this error when debugging:

Code: Select all

warning: Heap block at 0DCCA910 modified at 0DCCA919 past requested size of 1

Changing line 271 of COpenGLSLMaterialRenderer.cpp:

c8 *buf = new c8[maxlen];

to

c8 *buf = new c8[maxlen+1];

seems to fix the problem. I'm not sure exactly why Maybe something to do with a terminating NULL.

Hmm, the specs don't say anything about the extra null terminator at this place, but it won't hurt. So I'll add it to the service release of 1.6
