Hi all, We are using Kotlin + Spring to develop a web application. Recently, we observed the compilation is not stable and sometimes the build failed with StackOverflow exception. The kotlin version is 1.4.21-2 (the latest one) and we are using maven to build. The followings are the error messages. ``` [ERROR] java.lang.StackOverflowError at org.jetbrains.kotlin.cfg.ControlFlowProcessor$CFPVisitor.mark(ControlFlowProcessor.kt:174) at

Do I need to increase the stack size during compilation? If yes, how to do it in Maven? Thanks in advance. Regards, Yongqiang ---

I have figured out the solution by giving bigger stack size in `MAVEN_OPTS` ``` export MAVEN_OPTS="-Xms256m -Xmx1024m -Xss4m" ``` If you meet the same issue, hope it helps. ---

One more finding - If you have this issue in IDEA, you can use the environment variable of `_JAVA_OPTIONS`. ``` export _JAVA_OPTIONS=-Xss4m ``` I didn’t find how to configure in IDEA preference panel.
