Subject: tac: do not let failed allocation cause immediate exit
X-Git-Tag: v8.15~121
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1bb97e2aa16a247304c2492f6b52f2106259dbf4;p=platform%2Fupstream%2Fcoreutils.git

tac: do not let failed allocation cause immediate exit

* src/tac.c (temp_stream): Don't exit immediately upon failed heap
allocation, here.  That would inhibit processing of any additional
command-line arguments.
