@Vsevolod Tolstopyatov [JB] is it something known issue after upgrading to 1.4.3-native-mt:

'java.lang.Object kotlinx.coroutines.TimeoutKt.withTimeout-lwyi7ZQ(double, kotlin.jvm.functions.Function2, kotlin.coroutines.Continuation)'
java.lang.NoSuchMethodError: 'java.lang.Object kotlinx.coroutines.TimeoutKt.withTimeout-lwyi7ZQ(double, kotlin.jvm.functions.Function2, kotlin.coroutines.Continuation)'

on K/JVM (IR) target
K/Native and K/JS targets works well
project (rsocket-kotlin) has several dependencies with coroutines inside (ktor f.e.), is it because of it, or anything else?
is it related to changed mangling scheme for inline classes

[Paul Woitaschek]

@Oleg Yukhnevich Just hitting exactly that right now. Did you find a solution?

[Oleg Yukhnevich]

Not yet
I will create an issue and try to create minimal reproducer later today
