incorrect breakline parsing

[ityoung]

open class A(private val b: B) : C
(b) {

this will raise error: org.antlr.v4.kotlinruntime.misc.ParseCancellationException

but without breakline runs success:

open class A(private val b: B) : C(b) {

Hi,
thank you for reporting. I think this is a bug in the Kotlin ANTLR-Grammar, because kotlinx.ast is using a copy of this grammar to parse the kotlin source with antlr and this exception is comming from antlr.

I want to update this library in the next time, I will have a look at this issue then.
