I believe that the definition of timestamp_t as a union of timeval and
l_fp in parse.h is the root of these troubles.  If some code somewhere
in parseclock assigns a timespec to that union instead, that would
overwrite some stuff past that memory, I think.  But there's likely yet
another bug or wrong assumption in there somewhere that I don't have
time right now to hunt down.  The code in master has already eliminated
the union, but the bug is still there anyway.
