Bug 19954 – ICE: Casting AliasSeq to array and passing to a function

DMD64 D Compiler v2.086.0 Fedora Linux 5.1.5-300.fc30.x86_64 x86_64 Compiling this code causes dmd to crash, saying "Illegal instruction": enum String { STRING = "string", } void main() { import std.algorithm; import std.traits; assert((cast(string[])(EnumMembers!String)).canFind("none")); }

And it's a regression too : https://run.dlang.io/is/HlFXXK

Reduced example: void fun(string[]){} unittest { import std.meta : AliasSeq; fun(cast(string[])AliasSeq!""); }

even more: --- void main() { auto a = cast(char[][]) ""; } --- Attempt to fix leads to a past problem with CTFE : https://github.com/dlang/dmd/pull/9516#issuecomment-478227203
