Subject: Treat out of memory as error
X-Git-Tag: v2.42-start~241^2~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f79b2cf4177844fb64773a119f1cb1e41c8ccaf8;p=thirdparty%2Futil-linux.git

Treat out of memory as error

Otherwise it might happen that a configured file location is not taken
into account. A NULL value would lead to default file location.
