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: [email protected]
Reporter: [email protected]
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.)
