Has the problem been solved?

[brustolin]

@zhou934381967 Not yet. We will update this issue once it is resolved

[indragiek]

#3522

This will fix one of the crashes (the one in ThreadHandle::dispatchQueueAddress). The crash in sentry::profiling::backtrace needs a separate fix.

Any progress ? Very critical problem

Hello @skiryuk, which version are you using?
We're closely monitoring this issue, but for now, it has been extremely hard to reproduce, with a low rate of occurrence.
Any extra information is welcome.

[kahest]

for reference: we shipped a potential fix #4268 that is available in 8.35.0 and newer

We used version 7.14.0, with 8.9.0 and profiling =false stopped reproducing. Will try 8.35.0 and newer soon

got the same problem here using version 8.37.0, and received crash on iOS 17

@YuanSyuan, thanks for the update. Sharing more details with us makes it easier for us to fix this issue:

1. How often does this happen?
2. Can you reliably reproduce it?
3. Does it only occur on a specific set of devices?

After a few days of observation, this issue only occurred twice within a week, and we have not been able to reliably reproduce it. It happened once on an iPhone XR(iOS 17.6.1) and once on an iPhone 12(iOS 17.6.1).

Thanks again for the update @YuanSyuan 😃.
