Segmentation fault in other thread. I create thread using native linux functions: pthread_create(threadId.ptr, null, funRun, stableRef.asCPointer()) pthread_join(threadId.value, null), but if I call nativeHeap.alloc(...) or userdata, then I get Segmentation fault error

I solved problem. Need statement in new thread -konan.initRuntimeIfNeeded()

Please note that passing object between threads is currently possible only when you explicitly transfer them using workers API (https://github.com/JetBrains/kotlin-native/blob/master/runtime/src/main/kotlin/konan/worker/Worker.kt).

Also some details are available in “workers” sample: https://github.com/JetBrains/kotlin-native/blob/master/samples/workers/README.md

Svyatoslav, I see this worker, but it don't solve many tasks with thread, therefore I use native threads

[svyatoslav.scherbina]

Could you please provide more details? An example of task not solvable by workers?

[levcom]

I tried to rewrite using Worker, but I have a error after the successful completion function. Error: /home/jetbrains/kotlin-native-release/runtime/src/main/cpp/Memory.cpp980 runtime assert: Memory leaks found

Please try to add future.consume { ... } before worker termination.

Thanks, It works! Can I implement the function mutex for the operation? ex. pthread_mutex_lock(acceptMutex); val rc = FCGX_Accept_r(request.ptr); pthread_mutex_unlock(acceptMutex)

[svyatoslav.scherbina]

Could you please clarify your question?

[levcom]

Svyatoslav, thank you for your answers.
I want enforcing limits on access to a resource or function (eg. FCGX_Accept_r(request.ptr)).
Usually in the c language use mutex (I see in Worker kotlin object - locker). How can I synchronize access to a resource or functions within a body Worker?
