Nullable Double cast produces compiler internal error

I spent hours trying to find out why build failed whith this error on Elements 8.0.81.1667 (Visual Studio

  • Cocoa project):

Error 39 (E0) Internal error: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

I’ve found this error was produced by code like this:

var x:nullable Double;
var y:Single;
y:=x;

Please update the error message with a more descriptive one.

Thank you

Indeed. An internal error should never show.
