Bug ID: 19641
Summary: @try-@catch allows omitting return
Product: clang
Version: trunk
Hardware: All
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: Static Analyzer
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
When functions, Objective-C blocks, or methods which normally require a return
type contain the @try-@catch-@finally directives, no error is emitted if a
return statement is omitted.
id f() {
@try {
} @catch (...) {
} @finally {
}
// Expected error about missing return
}
- (id)g {
@try {
id var = (^id(void) {
@try {
} @catch (...) {
} @finally {
}
// Expected error about missing return
})();
} @catch (...) {
} @finally {
}
// Expected error about missing return
}
Clang still generates code as though there were, in fact, a return value for
the function.
