Thanks for opening the issue, @eric. We also see this in our internal SDK crashes.
How critical is this issue, as we would like to update to the letest version and what triggers it?
@bb-git, we haven't investigated what causes this yet. We see that this has happened from time to time for all SDK versions since 8.3.3
. So, I guess updating to any version later than 8.3.3
shouldn't make much of a difference.
Hi, I have a customer experiencing the same crash. Here's the stacktrace:
Signal: SIGSEGV
EXC_BAD_ACCESS (SIGSEGV): EXC_BAD_ACCESS (SIGSEGV)

The crash is affecting 0.2% of the users, mostly running on iPhone devices. Running Sentry React Native SDK 5.22.3
which runs cocoa 8.26.0
. We couldn't reproduce locally. Any advise on debugging?
@philipphofmann I have another customer experiencing a similar crash. Currently happening to a low number of users because Sentry is rolled out only to a low number of users, but concerned that this might grow significantly when Sentry is rolled out to all users.
