Yes, although I haven't looked at this particular PR.  I believe
that this is fixed in 3.3 and later.  All versions of gcc for the
32-bit port prior to 3.3 passed small 5-7 byte structures incorrectly.
They were left justified, rather than right justified as specified in
the ABI.  This is the cause of the reported truncation.  This only
shows up in code that has to inter-operate with code compiled with
the HP compiler and when using va_arg.

Dave
