Crash on pressing ` key (U+0060)

[colinux]

Hi,

on macOS, app instantly crash when pressing ` key (U+0060), in normal & insert modes.
(There is a dedicated key on french keyboards.)
I'm pretty sure this is a recent regression.

(editor start, I'm pressing `)

Tried with v0.4.13-18-ge6bdd81 from link Goneovim-latest-macos-5.15.2 (I don't know why there is also a 5.13.0 build).

[akiyosi]
