bumpalo breaks compilation

[Kirill Pinchuk]

I'm not sure if you actually want to fix this, posting it to save time for someone who get the same error
If you add memflow 0.2.0-beta7 to the fresh crate it doesn't compile and give this error:

error[E0500]: closure requires unique access to `self` but it is already borrowed

Fixed with: bumpalo = "=3.10.0"

Thanks for the report, totally happens here for me as well after i ran cargo update. So this is something that broke through semver. I'll have a look and report back when i updated it accordingly.

Alright, i yanked the 0.2.0-beta7 version and released 0.2.0-beta8 as a drop-in replacement (no feature changes). Can you please try with the new version?

@ko1N it works! 👍🏿
