           Summary: glGetUniformLocation does not work between glNewList
                    and glEndList
           Product: Mesa
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Mesa core
        AssignedTo: mesa-dev at lists.freedesktop.org
        ReportedBy: nbowler at draconx.ca

Calling glGetUniformLocation between glNewList and glEndList always returns 0,
even if the variable being requested does not exist in the program.

Occurs with at least swrast and i965.  I tested both mesa 7.8.2 and git master.
Restructuring the program so that the glGetUniformLocation is called outside
of the list makes it work.

For example:

  var = glGetUniformLocation(program, "something");
  /* var will now be zero, regardless of the program or "something" */
  /* do other stuff */
