 In util/support/utf8_conv.c, the SWAP16 macro is invoked with an
 argument that has side effects.  On platforms where SWAP16 can
 evaluate its argument twice (including platforms where utf8_conv.c
 creates a fallback definition for the SWAP16 macro), this can cause a
 read overrun by a factor of two.

 Rearrange the data flow to avoid calling SWAP16 with an argument that
 has side effects.
