Crash after gc sweep with asynchronous code

    XMLWordPrintable

Details

    Description

      I get a crash when running the attached code. I've tried to reduce the code as much as possible. A lot of our QML code is based on javascript Promise constructs, and it seems to be crashing when mixed with asynchronous C++ objects (like Timer, XMLHttpRequest...).

      Here is the trace I get with the qml tool, qtdeclarative build with valgrind config:
