* new ParentFlags is created, similarly to TryEmitMethodCall - this avoids unwanted propagation of IgnoreResult, MemberAccess, ... * handle ParentFlags.InstanceAccess - emit load address instruction * set closure.LastEmitIsAddress (this should be reset to avoid leaking this value from the emit of last argument) * handle IgnoresResult

Sorry, I tried fixing one NewExpression issue and it snowballed a bit.
I'm not sure how exactly ParentFlags is supposed to be used, and therefore unsure if my fix is right. However,
TryEmitMethodCalldoes not propagate any flags to its arguments, so it makes sense thatTryEmitNewExpressionshouldn't do that either. The rest of the changes inTryEmitNewExpressionis just handling of InstanceAccess and IgnoresResult parent flags.The removed
| ParentFlags.Ctorat 5084 seemed just like alternative solution for issue 333, which is now handled by not propagating InstanceAccess flag to constructor arguments.If you don't like this, feel free to point out any problems or just cherrypick the new unit tests (it's a separate commit) and fix them differently.
AI disclaimer: the unit tests were written with AI assistance (and I at least read all of it)
