--- Comment #2 from JxP <bugs at justexpired dot e4ward.com> 2013-01-17 17:24:52 UTC --- Created attachment 29195 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=29195 sample program not mixing iostream with stdio I confirm that using ios_base::sync_with_stdio(false) makes the original program run correctly (use argument 3 for that). However, I would expect that after commenting out all fprintf(stderr) lines, the program should work correctly even without that extra command (still use argument 2 for that), because then it doesn't explicitly use any stdio routines. But it doesn't. To see it fail now that we don't trace steps on stderr, follow the steps in the original post, use argument 2, then at the end type jobs to see the first cat still running. Why would the user be expected to ask iostream not to sync with stdio, if stdio isn't used?!
