Subject: Add a missing clear_current_lookup() call in recv_done()
X-Git-Tag: v9.19.0~15^2~2
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=2771a5b64da24ddbb385bfb4a5b6e3f5d2363a19;p=thirdparty%2Fbind9.git

Add a missing clear_current_lookup() call in recv_done()

The error code path handling the `ISC_R_CANCELED` code lacks a
`clear_current_lookup()` call, without which dig hangs indefinitely
when handling the error.

Add the missing call to account for all references of the lookup so
it can be destroyed.
