https://issues.dlang.org/show_bug.cgi?id=15882 Issue ID: 15882 Summary: writeln on a bad dstring triggering assert(0) in std.utf.toUTF8 Product: D Version: D2 Hardware: x86_64 OS: Windows Status: NEW Severity: enhancement Priority: P1 Component: phobos Assignee: nobody puremagic.com Reporter: erikas.aubade gmail.com So in trying to pass a UTF32 string from C++ to D, i think I've stumbled upon an issue in phobos. If the bad dstring is placed in a struct, and the struct converted to string, it returns the value x"8DA0000 51B5A8 67 69 74 65 63 68 20 57 69 6E 67 4D 61 6E 20 53 74 72 69 6B 65 20 46 6F 72 63 65 20 33 44 20 55 53 42"d, but if I try to pass the bad dstring to writeln, it triggers the assert(0) at the end of std.utf.toUTF8() (It's tricky to make a test snippet to send with this bug, because dmd will reject the string as bad unicode, so hopefully the literal is enough.) --
