X-Git-Tag: v9.21.15~9^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0e8c547e5b2410368a4e33cc082262d89a5762d0;p=thirdparty%2Fbind9.git

Test dig with a IPv4 source address and a IPv4+IPv6 server

Check that dig doesn't exit with an assertion failure when a IPv4
source address is defined after defining a server address which has
both IPv4 and IPv6 addresses (in this case, @localhost).
