            Bug ID: 17684
           Summary: clang and analyzer don't complain about implicit enum
                    to integer conversion even with -Weverything
                    -Wenum-conversion
           Product: clang
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Static Analyzer
          Assignee: kremenek at apple.com
          Reporter: mayer.julian at googlemail.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

neither clang nor the analyzer  complain about implicit enum to integer
conversion even with -Weverything -Wenum-conversion …. this piece of code
compiles without warnings although i'd like to see a warning in the if(...)
line


typedef enum
{
    MagicWithFairies = 10,
    MagicWithoutFairies = 11
} MagicValue;

MagicValue foobar()
{
    return MagicWithFairies;
}

void bla()
{
    if (foobar() == 10) // should be (foobar() == MagicWithFairies) as the enum
can change
    {
        printf("bla");
    }
}
