hm, with 2021-04-26-x86_64-unknown-linux-gnu, this crashes like this:

Hmm, I'm confused by the result of the bisection, I expected it to find a relatively recent commit since the reproducer doesn't ICE on stable (1.73) (while it does ICE on beta and nightly):

error: using function pointers as const generic parameters is forbidden

Doesn't ICE if generic_const_exprs is enabled.

[matthiaskrgr]

this feature fixing an ice instead of causing one, that's a first... 🙃
