    GLSL vertex shader compile sometimes fails


      I've been getting intermittent errors compiling a vertex shader, preparing for the first render of a newly created OpenGL context. It's the same vertex shader that usually works, on the same hardware. After glGetShaderiv detects the failure, the info log usually shows this:

      Vertex shader failed to compile with the following errors:

      Yes, that's the whole thing.  The video card is ATI FireGL V7700, and the GL_VERSION string is 3.3.11554 Compatibility Profile Context FireGL.  Any clues?
