             Bug #: 54441
           Summary: Infinite loop with brace initializer on zero-length
                    array
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: strikosn@gmail.com


Consider this:

struct s { char c[]; };

int main()
{
    struct s s = { .c = 0 };
    return 0;
}

Compiling with 'g++ -Wall h.c' gives infinite warnings:

h.c: In function 'int main()':
h.c:5:24: warning: missing braces around initializer for 'char [0]'
[-Wmissing-braces]
h.c:5:24: warning: missing braces around initializer for 'char [0]'
[-Wmissing-braces]
h.c:5:24: warning: missing braces around initializer for 'char [0]'
[-Wmissing-braces]
