It results in quite a cryptic error

```

(I tried all three compilers, happens in all)

Should I make an issue for this as it suggests?

100% yes. This an "Internal Compiler Error" (ICE), meaning the 
compiler has crashed.
Open a ticket here : 
https://issues.dlang.org/show_bug.cgi?id=23935

with a title like "ICE caused by std.sumtype", and paste the test 
case.
