false positive Wanalyzer-out-of-bounds in coreutils
When compiling coreutils with -fanalyzer enabled, a false positive
Wanalyzer-out-of-bounds underread warning is emitted in a complex flow. The
analyzer does think 'idx' can be 0 and thus, creates an offset_region with
offset - 1 in multiple locations. Logs attached.
