Summary: -w and switch returns = compile errors
Product: D
Version: 0.162
Platform: PC
OS/Version: Windows
Status: NEW
Keywords: diagnostic, rejects-valid
Severity: minor
Priority: P2
Component: DMD
AssignedTo: bugzilla digitalmars.com
ReportedBy: jpelcis gmail.com
char[] foo (int bar) {
switch (bar) {
case 1:
return "1";
case 2:
return "2";
default:
return "many";
}
}
Compiling this gives the following incorrect error message:
C:\programs>dmd -w test.d
warning - test.d(1): function test.foo no return at end of function
Severity is minor because there are at least 3 easy workarounds:
Use if-else.
Assign to a temporary variable and return that outside of the switch.
Place a return immediately after the switch.

Probably part of the same bug: If you add a statement after the switch, it
fails to report "statement is not reachable".
