A regression was introduced in the latest D1 changeset: b75d921 merge D1 pull #529 https://github.com/D-Programming-Language/dmd/commit/b75d921 When compiling tango I get this error which didn't happened before: ./tango/io/vfs/ZipFolder.d(672): Error: undefined identifier __result Unfortunately I couldn't come up with a minimal test case yet, but since I know the exact commit that caused it, maybe it is easy enough to be fix by somebody familiar with what that patch does.
Oh, and it only happens with -release!
Reduced test case applies also to D2, and doesn't require -release: =========================================== struct Container8073 { int opApply (int delegate(ref int) dg) { return 0; } } class Bug8073 { int foo() out { } body { Container8073 ww; foreach( xxx ; ww ) { } return 7; } } =========================================== It's because with func->result is used for 'foreach' as well as for out contracts. If it's used in a foreach, it currently doesn't get added to the out contract scope 'scout'. In statement.c, ForeachStatement and ReturnStatement need if (func->scout) func->scout->insert(vresult); in both places where they create vresult.

Thanks for your reduced test case and description! I have posted a D2 pull to fix it: https://github.com/D-Programming-Language/dmd/pull/946
