Thanks for the testing. I'm applying this workaround:


2017-05-19  Bruno Haible  <address@hidden>

        printf-posix tests: Avoid test failure with "gcc --coverage".
        Reported by Tim Rühsen <address@hidden>.
        * tests/test-printf-posix2.c (main): Test a width of 10000000 rather
        than 5000000.
        * tests/test-fprintf-posix2.c (main): Likewise.
