Subject: curl_multi_cleanup: ignore SIGPIPE better
X-Git-Tag: curl-7_37_0~77
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=37f484276d863347df2616ead1524bffc2257098;p=thirdparty%2Fcurl.git

curl_multi_cleanup: ignore SIGPIPE better

When looping and closing each individual connection left open, the
SIGPIPE ignoring was not done and could thus lead to death by signal 13.
