--- Comment #3 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
With valgrind 3.7.0 and gfortran 4.9.0 r208594, I no longer see the

Conditional jump or move depends on uninitialized value

if I don't use -flto, while I still see them with 4.8.2. Note the errors are
back for 4.9 if I compile with -flto.

I all cases I see some "... blocks are still reachable in loss record ..."
messages related to I/Os (in write_float).
