Unsolved

Hi My Qt application encountered this error after running for a long time (probably a couple of hours):
*** stack smashing detected ***: terminatedI know there must be some stack overflow issues but I'm not sure how to debug it.
The debug mode in QCreator shows the following log but I cannot figure out where it it exactly causing the problem. Anyone help me? Thanks in advance.

@dalishi said in How to debug *** stack smashing detected ***: terminated:
void doActivate<false>(QObject *, int, void * *)
What is it doing?
