Hi Justen, I tested the latest piglit and found lots of crashes(Over three thousand) on both AMD and NVIDIA. This might be caused by your commit b28cdc887aefb1e766719e1f74d457f77bdf9a18 on shader_runner.c.
According to page 363 and 360 of glspec44.compatibility for glVertexPointer: "An INVALID_OPERATION error is generated if a non-zero vertex array object is bound, no buffer is bound to ARRAY_BUFFER, and pointer is not NULL." So if app who wants to use VAO, should obey the following gl call sequence: glGenVertexArrays glBindVertexArray glGenBuffers glBindBuffer glBufferData glVertexAttribPointer But now the red part missed under current code path when use_fixed_function_attributes and INVALID_OPERATION was returned by subsequent glVertexAttribPointer. Then both AMD and NVIDIA crashed on subsequent glDrawArrays. Besides, mesa driver's gl_version=30 so it followed another code path which didn't use VAO, and had no crash.
