QHash static member error

[ramazangirgin]

when running with gdb it gives that output:


[Thread debugging using libthread_db enabled]
[New thread -1499507024(LWP 24685)]

Program received signal SIGSEGV Segmentation Fault

[Switching to thread -1499507024(LWP 24685)]

You have to protect the hash for example with QReadWriteLock if you access it from multiple threads.

[ramazangirgin]

No i am using in only one thread since I think lock isn't necessary.

So what does the backtrace look like? Could you provide something compilable we could test ourselves?

[marcel]

I believe the static QHash is instantiated before QApplication.

I believe the static QHash is instantiated before QApplication.

That shouldn't be any problem. QHash is not a QObject but a generic container, it doesn't depend anyhow on the application object.
