Description Matthias Clasen 2005-03-07 06:45:06 UTC

When compiled with gcc4, pkg-config --help crashes due to an overflow in the
format string in singleOptionHelp.

Comment 2 Stanislav Brabec 2005-05-24 07:34:02 UTC

char format[11] should be enough.

Can anybody commit the fix for this crasher?

        * popthelp.c: char format[10] overflowed always with gcc4, so use
        positional parameters instead.  Thanks to Scott James Remnant for
        pointing me to that solution.  Debian #321961, Ubuntu #13950,
        Freedesktop #2661
