Subject: perl plugin: Do not pass NULL to newRV().
X-Git-Tag: collectd-4.6.0~10
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=90760db56fa3fe54e1aa99d7c6914b544b1bf16d;p=collectd.git

perl plugin: Do not pass NULL to newRV().

newRV() does not handle that correctly and causes a segfault instead. Now, we
use PL_sv_undef instead.
