Thank you, I was able to reproduce the bug with these instructions.
The
bug doesn't show up in 9.5.1b3, which is due to be released in a
couple
of days. I believe this is attributable to the following fix:
2470. [bug] Elements of the isc_radix_node_t could be
incorrectly
overwritten. [RT# 18719]
This one may have been a factor as well:
2474. [bug] ACL structures could be allocated with
insufficient
space, causing an array overrun. [RT #18765]

Thanks for the update.
I could reproduce this against 9.5.0-P2.
I could not reproduce this against 9.5.1b2.

Regarding these additional informations, i took a look at differences
in file radix.c. As i presumed, most changes occurs in fonction
isc_radix_insert().
As a quick fix, i try to only apply the changes from radix.c in
9.5.0-P2 and the segv has gone. The patch is short and seems to not
have any other side effects.
Cheers,
