Subject: pgsql: Clear errno before calling strtol() in spell.c.
Date: Sat, 08 Mar 2025 16:25:16 +0000
Message-ID: <[email protected]> (raw)
Clear errno before calling strtol() in spell.c.
Per POSIX, a caller of strtol() that wishes to check for errors must
set errno to 0 beforehand. Several places in spell.c neglected that,
so that they risked delivering a false overflow error in case errno
had been ERANGE already. Given the lack of field reports, this case
may be unreachable at present --- but it's surely trouble waiting to
happen, so fix it.
