/** @file arb_es2_compatibility-releasecompiler-ge7.c
*
* This tests glReleaseShaderCompiler() between compilation and linking.
*
* At the time of writing, this causes Mesa to crash with Google Earth
* version 7 because the linker is trying to use data that was
* generated by the compiler but freed by glReleaseShaderCompiler().
*
* This test passes with NVIDIA's driver.
*
* The vertex/fragment shaders are captured from Google Earth v7.
* Simpler shaders don't always trigger the bug we're testing for.
