Reverting to 1.3.6 fixes the crash (but it has the #2004, which has a workaround)

It happend to me when I used coroutines- withContext in 1.3.7 to 1.3.8 on Android/Flutter, revert coroutines lib to 1.3.6 , the app does not crash anymore.

Unfortunately, this is a bug in Kotlin compiler related to function with contracts that were added in #2030.

We are working on the fix, a workaround is to extract withContext calls from try and catch blocks (I’ll try to post more specific workaround later) to separate functions. Sorry for the inconvenience!

It’s happening with Android Gradle Plugins 3.6.2, 3.6.3 and 4.0.0-rc01, so I think it’s not caused by D8/R8.

Also, it’s happening with debug builds, and I think they are not using R8 in default configuration.

Fixed in 1.3.9 with Kotlin 1.4

Changing kotlin_version to 1.4.0-rc solved the problem.

I confirm that a similar problem https://youtrack.jetbrains.com/issue/KT-39298 is not reproduced with Kotlin 1.4-M2. The bug with contracts mentioned above was fixed in 1.4-M2.
