Here is the log output from the failing pg_regress after enabling checkpoints and timestamps:

And I do see the tblspc file left after the finish of "make check":
tmp_check/data/pg_tblspc/16385/PG_9.3_201212081/16384/16387

PS I wouldn't be surprised that it is a compiler bug though. But I did see the
failure with newer icc as well.
