I am using a (very) low-end graphics adapter (intel g31).

I am writing an OpenGL program that uses VBOs and shaders (GLSL 1.2). The program compiles flawlessly but then when it calls glLinkProgram(), an exception is thrown:

Unhandled exception at 0x1027101A (ig4icd32.dll) in Test.exe: 0xC0000005: Access violation reading location 0x00000000.

I used glew’s glewinfo.exe and OpenGL Extensions Viewer to see whether glLinkProgram() exists — and it does exists. Also other closely related functions (glCreateProgram(), glCreateShader(), glCompileShader(), etc.) works and works as intended.

What could be the actual source of the problem? Is it a problem or a bug of glew? Is it a problem of my driver?

I have set glewExperimental to GL_TRUE which solved many of my other problems.

EDIT: I have also used glLinkProgramARB() and produces the same error as above.

    Given that ig4icd32.dll is Intel’s driver, and that’s where it’s crashing, I’m guessing that Intel’s driver is crashing.

    It shouldn’t do that, but don’t feel bad. Intel’s pretty well known for bad OpenGL drivers. Best to avoid them wherever possible.
