Subject: su: add segmentation fault reporting of the child process
X-Git-Tag: v2.23-rc1~683
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ea8a10391b9cba4b472d843b7108c0b140a392ab;p=thirdparty%2Futil-linux.git

su: add segmentation fault reporting of the child process

Child processes that ended with segmentation fault previously
indicated this with return status only. The report is now more
verbose if core dump is allowed.
