Description
- Launch the application with qmljsdebugger=port:3768, block (the app waits for connection)
- In Qt Creator, use Attach to QML Port
- Any breakpoint I set is then hit, I'm happy, I can see some context.
- On a very simple project, I can hit step out, into, etc, and continue. But on larger projects, as soon as I try to continue, the execution hangs. I then attach to the process using Visual Studio.
- I hit pause
- The execution seems to be running in an infinite loop while executing
ArgumentCollectJob::run() at line 285 of qv4debugging (statement is collector->collect(qName, v)
- qName here has the name of a property in the breakpoint's context. nFormals is 30 and i is 0.
- follows what appear to be an infinite recursion of calls to
-> Qt5Qmld.dll!QV4::Debugging::Debugger::Collector::collect(const QV4::ObjectRef object) Line 746 C++ -> Qt5Qmld.dll!QV4::Debugging::Debugger::Collector::collect(const QString & name, const QV4::ScopedValue & value) Line 719 C++ -> Qt5Qmld.dll!VariableCollector::addObject(const QString & name, QV4::ValueRef value) Line 255 C++
