ILC throws an IndexOutOfRangeException

[filipnavara]

Issue #123833 noted an error in the ILC compiler that was fixed in PR #123911.

We are hitting the same problem in .NET 10 (also using the WeCantSpell.Hunspell library, just on macOS):

Error: Index was outside the bounds of the array.
System.IndexOutOfRangeException: Index was outside the bounds of the array.

Perhaps the fix should be backported?
