Well, it's not working for me even when I remove preview=in

But my error messages are different(ldc 1.25.0 based on dmd 2.095.1):


Error: none of the overloads of this are callable using argument types (),
candidates are:


/usr/lib/ldc/x86_64-redhat-linux-gnu/include/d/object.d(2140):
object.Exception.this(string msg, string file = __FILE__, ulong line =
cast(ulong)__LINE__, Throwable nextInChain = null)


/usr/lib/ldc/x86_64-redhat-linux-gnu/include/d/object.d(2145):
object.Exception.this(string msg, Throwable nextInChain, string file =
__FILE__, ulong line = cast(ulong)__LINE__)

(whitespace inserted by me)

Of course, providing a string argument to Exception solves this, preview=in or otherwise.

Oh, and -inline makes no difference for me.

You can try it on
https://run.dlang.io/is/w2P2tQ
It makes difference, maybe your compiler is outdated / etc

Yeah that error is coming for me on dmd 2.097.1

Maybe regression?

@Geod24 created dlang/druntime pull request #3592 "[stable] Fix 22283: Weird error in object with inline and preview=in" fixing this issue:

- Fix 22283: Weird error in object with inline and preview=in

  This happens because preview=in uses a 'stronger' version of 'in',
  which makes 'scope const' and 'in' parameters not covariant.
  Why it triggers with '-inline' and not without is anyone's guess.
