ATS crash 7.1.6 #5596
Description
Hi,
Running into an ATS crash when running with 7.1.6 versions. I have a custom plugin using atscppapi along with the base trafficserver. The same plugin worked without any issues on 6.2.{1.3} without any issues. Upgrading the base to 7.1.6 result with everything else remaining the same results in this crash. The backtrace is pasted below...
OS: Ubuntu 16.04
Please let me know if you need any additional info...
