--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Running this under valgrind I see 900+ errors, the first 100 seem to be from
the global strings in the libstdc++-v3/testsuite/util/testsuite_fs.h file (I
think).

All the errors are basically nonsense, reporting errors in getpid() and
mkstemp() and things that are very unlikely to be broken, so either that
executable is horribly miscompiled or valgrind is useless with it.
