--------------------------------------
Summary: ConcurrentStlMap - stl map find crash with empty map
Key: AMQCPP-527
URL: https://issues.apache.org/jira/browse/AMQCPP-527
Project: ActiveMQ C++ Client
Issue Type: Bug
Components: Decaf
Affects Versions: 3.8.1
Reporter: Christian Mamen
Assignee: Timothy Bish
Recently experience a crash while an activemq work thread attempts to remove a
temporary destination from a ConcurrentStlMap. This crash happens inside a
std::map::find() when the map is currently empty.
{code}
virtual V remove(const K& key) {
V result = V();
synchronized(&mutex) {
typename std::map<K, V, COMPARATOR>::iterator iter =
valueMap.find(key);
if (iter == valueMap.end()) {
return result;
}
[...]
{code}
I look arround in forums and found that some people do experience similar
problems with stl map.

http://www.velocityreviews.com/forums/t278300-std-map-find-throws-exception-when-map-is-empty.html
so it appears that this error might be an stl issue, (perhaps platform
related?). The workaround suggested is the check if the map is empty before
performing a find.
The stack trace i got
