My mistake - you only get the second part of the report if the
uninitialised value is in memory. If it's in a register then you
don't as there isn't much to say.

Your best bet in that case is to inspect the code at the failing
location and see if there is an obvious cause, and if not then to
try inserting some assertions using the valgrind macros to try and
work out what is uninitialised - assertions like this will do it:

  assert( !VALGRIND_CHECK_READABLE( &variable, sizeof( variable ) ) );
