glDrawArrays() is a standard OpenGL 1.1 function, which does not belong to GL_EXT_compiled_vertex_array extension: https://www.khronos.org/registry/OpenGL/extensions/EXT/EXT_compiled_vertex_array.txt

The crash happened on Intel HD Graphics 520 + Mac OS X 10.13.3, as pglDrawArrays is a NULL pointer if GL_EXT_compiled_vertex_array does not exist.

Yes, it seems a mistake. Merging.
