I just stumbled across yet another bug in the M32 optimizer
used in DMD SGS rel. 2.0.  This one has ops[0] (opcode) of
a node getting overwritten with ".L169" (a label in the
assembly code being optimized) -- note that is not the
location pointed to by ops[0], as usual, but the pointer
ops[0] itself is getting DATA stored on it!  I looked at
the strcpy()s but didn't spot the bug.  If anyone knows
what is causing this one, please let me know!
