Hi, I have a question about ByteArray and toMutableList() method, on new Kotlin 1.3.50 when i do (in Common):
```
val bytes = byteArrayOf(1)
val mutableBytes = bytes.toMutableList()
```
It works fine, but if a byteArray contains negative value i got a crash on iOS (on Android works fine). It's easy to reproduce, example:
```
val bytes = byteArrayOf(-1)
val mutableBytes = bytes.toMutableList() /* got a crash here on iOS */
```
Does anybody have this issue?

Can you report it in Kotlin/Native's GitHub issues?

Hello <@UJP5WKLSZ>! This problem looks similar to this one: <https://github.com/JetBrains/kotlin-native/issues/3290>
Please try to use the workaround described in the discussion.

_Please try to use the workaround described in the discussion._ - Thanks for reply, but the solution didn't help

Created the issue in Kotlin/Native's GitHub: <https://github.com/JetBrains/kotlin-native/issues/3355>

Can you confirm that workaround made no help here? I have reproduced the issue with the same conditions, and it was gone as I corrected the `konan.properties`.
