This bug, PRIx16 is "x" rather than "hx", reported 2012-08, has just bit me.
Is Ubuntu now doing a disservice to the community by still accepting bug reports, but acting as a "nothing happens" sink for them with more chance of a fix if they were reported upstream in the first place?

Title:
  stdint.h defines PRIx16 and similar in unhelful way

Status in eglibc package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 11.04
  reference: http://pubs.opengroup.org/onlinepubs/007904975/basedefs/inttypes.h.html

  inttypes.h defines macros for fixed integer types.  The ones for 8-
  and 16-bit types are currently the same as the 32-bit types, which
  pretty much makes them useless.

  PRIx16 is x      I suggest it should be hx
  PRIx8 is x        I suggest it should be hhx

  Otherwise, only by excruciatingly correct typecasting in the printf can you get the correct output for something like
  int16_t this = -1;
  printf("%" PRIx16 "\n", this);

  As it stands, it will print 8 hex digits.  It makes more sense for it
  to print 4.
