Subject: pbx_variables: initialize uninitialized variable
X-Git-Tag: 16.24.0-rc1~49
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ffb98d764c00e925a445a70562ab49e0ae24d88a;p=thirdparty%2Fasterisk.git

pbx_variables: initialize uninitialized variable

The variable cp4 in a variable substitution function
can potentially be used without being initialized
currently. This causes Asterisk to no longer compile.

This initializes cp4 to NULL to make the compiler
happy.
