If i add the -O compiler flag to the second example it compiles 
without error.

Any ideas what could be the problem? I haven't tried the ldc2 
executable because i need rdmd to correctly gather the 
dependencies.

Hm. Could you please provide some more details? LLVM version, OS, 
...

I think this is issue 454 
(https://github.com/ldc-developers/ldc/issues/454).

We are going to need some kind of test case to be able to track this down.

Here's a simple test case, save as file.d

         import std.stdio;
         import std.file;

         void main()
         {
                 auto entries = dirEntries(".", "*", 
SpanMode.shallow, false);

                 writeln("crashes before this compiles");
         }

Compile with: rdmd --compiler=ldc2 file.d

Error:

Thanks for your efforts, but we already had a test case for that bug
in the linked bug report. That's also why I quoted the other one in my
earlier message, the crash in AndAndExp::toElem. There, we don't know
anything besides the fact that there *might* be a problem in
AndAndExp::toElem (possibly another i1/i8 issue?).

Cheers,
