  I just tested it. Since type punning is only done throw unions, it should
not be required... but please add -fno-strict-aliasing to $CFLAGS and it
will work.

  It fails with default rpm %optflags due to generating invalid code, when
not properly updating the pointer where lightning writes instructions to,
and generating invalid opcodes.
