Hi,

I am using CommonAPI dbus for my application. In application (x86), I have use case to get the attribute from server using async call. When I execute async call, it leads to crash at client side.
This crash behavior is seen if the attribute is configured as "DBusDefaultAttributeType = freedesktop" and observed for attribute type uint and int. Similar tested for string and bool attribute type, issue behavior is not seen.

For experiment, I have tried https://github.com/GENIVI/capicxx-core-tools/tree/master/CommonAPI-Examples/E02Attributes example application and added get attribute async call. Still the crash issue is observed.

Please find the library versions used in application,
CommonAPI core - 3.1.12.6
CommonAPI dbus - 3.1.12.11
dbus - 1.10.10

Crash call stack log available below,
