10.0.0-rc1 difficult to track down crash

See original GitHub issue

Hi there, any advice on how I can track down a crash on code that works fine with react but breaks in preact - is it possible to force webpack/babel to use the source dist of the module rather than the dist? The error is Uncaught (in promise) TypeError: Cannot read property 'call' of undefined at y.r [as shouldComponentUpdate... but I cannot figure out the call process properly from the minified code to give you a decent bug report?

The issue seems to be caused when a ref is added to a memo’ed component that did not have a ref in the previous render. The next release should make things work again for you 😃
