Environment

SaaS (https://sentry.io/)

Steps to Reproduce

In my App, I use iOS SDK of 8.7.1 version.

in Podfile pod 'Sentry', :git => 'https://github.com/getsentry/sentry-cocoa.git', :tag => '8.7.1'

the backtrace belows:

0 ??? 000000000000000000 000000000000000000 + 0 1 Sentry __50-[SentryDispatchQueueWrapper dispatchAfter:block:]_block_invoke + 40 2 libdispatch.dylib __dispatch_client_callout + 20 3 libdispatch.dylib __dispatch_continuation_pop + 504 4 libdispatch.dylib __dispatch_source_invoke + 1588 5 libdispatch.dylib __dispatch_lane_serial_drain + 376 6 libdispatch.dylib __dispatch_lane_invoke + 384 7 libdispatch.dylib __dispatch_workloop_worker_thread + 652 8 libsystem_pthread.dylib __pthread_wqthread + 288

Expected Result

I try to fix ,but no work:

• (void)dispatchAfter:(NSTimeInterval)interval block:(dispatch_block_t)block { dispatch_block_t _block = [block copy];

    dispatch_time_t delta = (int64_t)(interval * NSEC_PER_SEC);
    dispatch_time_t when = dispatch_time(DISPATCH_TIME_NOW, delta);
    dispatch_after(when, _queue, ^{
        @autoreleasepool {
            if (_block) {
                _block();
            }
        }
    });
  

}

Hello @kidGuo, thanks for reaching out. Can you reproduce this in a clean project? I cant reproduce this, if you could share a repro would helps us a lot.

I'm sorry, I'm unable to reproduce it in a clean project. Even in our app, I haven't been able to reproduce it. All I can see is the crash logs reported by users.

[brustolin]

Thanks, we will keep investigating.

We did not manage to reproduce this. We need more reports to be able to investigate this further.
