    intermittent GLSL shader compile errors


      I've been getting occasional shader compile errors on a machine with an ATI FireGL V7700 card (driver date 2/24/2012).  When glShaderiv( *, GL_COMPILE_STATUS, * ) reports that the compile has failed, I call glGetShaderInfoLog, and the message I get is:


        Vertex shader failed to compile with the following errors:


      That's the entire message.  Not too helpful.  The vertex shader is not especially complex, and usually compiles successfully.  Any idea what could cause that?
