        <pre>I just tried that (signed fields ahead of unsigned) and it didn't help in this
case.  The modified struct began as:

struct prog_src_register
{
   GLint Index:(INST_INDEX_BITS+1); /**< Extra bit here for sign bit.
                                     * May be negative for relative addressing.
                                     */
   GLint Index2:(INST_INDEX_BITS+1); /**< Extra bit here for sign bit.
                                       * May be negative for relative
                                       * addressing. */
   GLuint File:4;    /**< One of the PROGRAM_* register file values. */
   GLuint Swizzle:12;
. . .
}</pre>
