TreeView: Maximum call stack size exceeded error - Siblings #230361
Description
Max call stack error when there's too many nodes in a TreeView
Steps to Reproduce:
- Install JSON TextMate extension
- Load a file that causes a TextMate grammar to match many many rules
typename::std::add_pointer<typename::std::add_pointer<typename::std::add_pointer<typename::std::add_pointer<typename::std::add_pointer<typename::std::add_pointer<typename::std::add_pointer<typename::std::add_pointer<typename::std::add_pointer<int>::type>::type>::type>::type>::type>::type>::type>::type>::type ptr{nullptr};
works well in a CPP file - right click =>
Show TextMate Calling Stack - wait for file to be parsed
- wait even longer for VSCode to attempt to render the tree (notice memory usage going up)
- Max Call Stack error
ERR Maximum call stack size exceeded: RangeError: Maximum call stack size exceeded
