Crash during destruction when using meta_function::new_index and coroutines #1594

Open Maddimax opened 3 months ago

Maddimax commented 3 months ago

I attached a reproduction example to the ticket: main.cpp.txt

The example crashes during the m_entries.clear(); in the ~MyDynamic() destructor.

The crash only occurs if the test() function is started as a coroutine.

I sadly don't know enough about lua to see if this is a problem with lua itself, or something in sol2. Any help/hints would be greatly appreciated.

Build and reproduced on macOS 14,
