[jira] [Created] (DISPATCH-378) Seg Fault in CORE_link_push
Gordon Sim created DISPATCH-378:
-----------------------------------
Summary: Seg Fault in CORE_link_push
Key: DISPATCH-378
URL: https://issues.apache.org/jira/browse/DISPATCH-378
Project: Qpid Dispatch
Issue Type: Bug
Affects Versions: 0.6.1
Environment: Latest master branch of dispatch, fedora 23
Reporter: Gordon Sim
Doing some perf testing with a very simple two router setup, one router connecting to the other. Hit this once only so far (i.e. not readily reproducible) wasn't doing anything noticeably different at the time.
{noformat}
Core was generated by `./sbin/qdrouterd --conf ./etc/qpid-dispatch/router2.conf'.
Program terminated with signal SIGSEGV, Segmentation fault.
