truss output of echoping sig11 on 11.0-RELEASE amd64

Problem appears to possibly be program bug in echoping but may be clang. SIG11 occurs after munmap() call and only occurs on amd64. No problems were observed on i386 or aarch64. No other symptoms have been observed yet but http and https work without problems.

I can't reproduce

% echoping -m dns ns1.isc-sns.net www.freebsd.org
Elapsed time: 0.035630 seconds
% uname -a                                       
FreeBSD nihayet.local.arved.priv.at 12.0-RELEASE-p10 FreeBSD 12.0-RELEASE-p10 GENERIC  amd64

The command output from your truss output doesn't even work: 

/usr/local/bin/echoping -t 5 -m /usr/local/lib/echoping/dns.so -n 20 -t A nsd0.rootlair.pvt
Error: Unknown type

Phillip, is this still happening on newer FreeBSD versions?
