Escape analysis failure: Please try to disable escape analysis and rerun the build. To do it add the following snippet to the gradle script: kotlin.targets.withType<org.jetbrains.kotlin.gradle.plugin.mpp.KotlinNativeTarget> { binaries.all { freeCompilerArgs += "-Xdisable-phases=EscapeAnalysis" } } In case of using command line compiler add this option: "-Xdisable-phases=EscapeAnalysis".
