"CLR detected an invalid program" exception

Hello,

Postprocessed version of expression without a long definition of input type:

(System.Object)(.If ( ((INPUTTYPE)$displayType).param_13 != null && ((INPUTTYPE).param_14 != null ) { ((INPUTTYPE).param_14 } .Else { null } || .If ( ((INPUTTYPE)$displayType).param_13 != null && ((INPUTTYPE)$displayType).param_15 != null ) { ((INPUTTYPE)$displayType).param_15 } .Else { null }

Following program compiles without an issue but invoking it causes "CLR detected an invalid program" exception

Sorry for bad code insertion. blame github :)

@Exmirai Could you provide the expression in form Exression.Convert(Expression.IfThen(...), typeof(object)) etc.?
And even better, the isolated failed test.

Closing without the requested info provided

@dadhi Sorry for inconvinience. Here's the sample code:

`
var p1 = Expression.Condition(Expression.Equal(Expression.Constant(true), Expression.Constant(true)), Expression.Constant(null, typeof(Nullable)), Expression.Constant(null, typeof(Nullable)));

var p2 = Expression.Condition(Expression.Equal(Expression.Constant(true), Expression.Constant(true)), Expression.Constant(null, typeof(Nullable)), Expression.Constant(null, typeof(Nullable)));

var expre = Expression.Convert(Expression.OrElse(p1, p2), typeof(object));

var l = Expression.Lambda<Func>(expre);

var fast = l.CompileFast();
var ord = l.Compile();

var y = ord();
var x = fast();`

fast() method fails, ord() does not

Thanks for the info. Will look into it.
