[openrtm-users 01191] Problem shutting down component when more then one connection exists

[Steffen Wittmeier]

Hi,

I receive a seg-fault when calling cleanupComponents(). The problem only 
occurs in the following setups (see also attached screenshot).

If component A (here LogViewer) is destructed by calling exit() on the 
component and cleanupComponents() on the manager (somehow 
cleanupComponent(rtc) does not call the destructor?) and this component 
A is connected to a port of component B (LogManager) which is turn 
connected to a component C (EcceosModel) I receive the seg-fault.

In contrast, if I remove the connection between component B and C and 
call exit() on component A, the application exits normally.

I attached a backtrace of the seg-fault. You can see that I am calling 
cleanupComponents() that leads to the destructor call of the PortProfile 
which causes the error.

Is this some internal error where you could provide a fix for? As I 
receive the same error when I exit the component A in the 
RTSystemEditor, it seems that it is not a problem of the component 
deletion within my code.

Any help is appreciated...


Many thanks in advance,
Steffen Wittmeier
