Ok for trunk?

Yes; thanks.

(fwiw I added this test during the development of r16-6063-
g0b786d961d4426 as a regression test for an ICE I temporarily
introduced in earlier versions of that patch).

Without -Wno-overflow, for arm-none-eabi targets, I see warnings
like:
coreutils-group_number.c:13:21: warning: conversion from 'long long
unsigned int' to 'size_t' {aka 'unsigned int'} changes value from
'18446744073709551615' to '4294967295' [-Woverflow]

Looks like this PR 123191 ?

Thanks,

Christophe
