'Common Language Runtime detected an invalid program' with int.TryParse

[SteveWilkes]

Hello!

I'm getting a 'Common Language Runtime detected an invalid program' error thrown when I invoke a fast-compiled Func consisting of a single block with a single variable which it populates and returns like this:

int intValue;
int.TryParse("123", out intValue) ? intValue : default(int);

I've created a repro repository here.

Cheers!

Steve

Thank you for creating a repo.
Just for the future, you may just add the ignored failing test into tests\FastExpressionCompiler.IssueTests project. You may look at other tests in this project for example.

Cheers, will do! :)

I've included the test.

But it does not work yet.
there was an error in condition, wich I fixed.
but there are errors with the ref parameter emit, 3 nop's are inserted.

It's because in closure.GetDefinedLocalVarOrDefault(paramExpr); it does not find the Variable, cause the Variable is changed via MakeByRefParameters(expr, expr.Arguments)

@dzmitry-lahoda maybe you could look after this, think most of the byref code is from you? Atm, I've no good idea how to fix

[dzmitry-lahoda]

Awesome, thank you :)

I've updated my copy of the code from the latest in master and it now works. Thanks!

close?

I'm happy for the issue to be closed - wasn't sure if you close issues once master is updated / once NuGet is updated, etc.
