You don't need to add the three dots everywhere since we really don't
want to wipe out low order digits just for the fun of it. The "..."
means "match anything", so if only the last digit or two are different
replace them by "..." - there is no need to replace a certain number
of characters.

I am seeing that one too, but I cannot hit it on x86-64. I have made
this #4091. Feel free to open a ticket for the numerical noise fuzz
failure.
Cheers,
