Subject: Initialize variable before use.
X-Git-Tag: elfutils-0.164~36
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fc0a0f303bf31194c9cef9bb6a766cec9d7794fb;p=thirdparty%2Felfutils.git

Initialize variable before use.

Some compiler does not know that error function never returns.
