Long hang on application termination

[tuli]

When i perform certain actions with my program, the program hangs for ~10-15 seconds on termination, at 100% cpu usage.

The main thread is destrying a custom object (as it should), but appears to have some issues within the destructor of an

typedef QMap<quint64, QSet< quint64> > trzf_cache;

typedef QMap<quint64, QSet< quint64> > trzf_cache;

object.

So the hang happens within Qt-map code.

Any ideas how any of my code could cause this?

Describe "certain actions".

How can you tell that the delay is in QMap code?

That will be a wild guess , unless we see code.
