Jonathan,
There are actually a second of instance of this warning....
/sw/src/fink.build/llvm37-3.7.0-100/llvm-3.7.0.src/projects/openmp/runtime/src/kmp_i18n.c:918:9:
warning: default label in switch which covers all enumeration values
[-Wcovered-switch-default]
default : {
^
but at least in this case the default case is at the end of the switch
statement.
switch ( severity ) {
case kmp_ms_inform : {
format = kmp_i18n_fmt_Info;
} break;
case kmp_ms_warning : {
format = kmp_i18n_fmt_Warning;
} break;
case kmp_ms_fatal : {
format = kmp_i18n_fmt_Fatal;
} break;
default : {
KMP_DEBUG_ASSERT( 0 );
};
}; // switch
