SUGGESTED FIX

Add LP64 specific code that removes the empty slot and chooses the right one for conversion.

It seems I have never verified the test of 6991596 with 64-bit SPARC.  On SPARCV9 a long has two 64-bit interpreter slots but the value is passed only in one slot.  The current code does not handle this.
