Use of transform-runtime + proposal-decorators plugins causes Maximum call stack size exceeded #9127
Description
Bug Report
Current Behavior
The use of @babel/plugin-proposal-decorators together with @babel/plugin-transform-runtime generates a bundle that causes a infinite loop (around _typeof() and _typeof2() eventually causing the browser to throw Uncought RangeError: Maximum call stack size exceeded.
If I remove transform-runtime from the configuration, the bundle generated does not emit any errors.
Input Code
- REPL or Repo link if applicable:
class Foo {
@propDecorator
get method1() {
return "one";
}
}
function propDecorator(d) {
return d;
}Expected behavior/code
The transformed code should not cause an infinite loop
