Subject: fix failure of getdelim to set stream orientation on error
X-Git-Tag: v1.1.21~87
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=5cd309f0cc3c92f3fabbaa499652a8329137c4de;p=oweals%2Fmusl.git

fix failure of getdelim to set stream orientation on error

if EINVAL or ENOMEM happened before the first getc_unlocked, it was
possible that the stream orientation had not yet been set.
