Crashing Breakout rooms

Description
The iOS Zoom SDK randomly crashes as we leave and re-enter a breakout room. It usually takes about five or six round trips. But after that, for example:

Thread 34: EXC_BAD_ACCESS (code=1, address=0x0)
MobileRTC`___lldb_unnamed_symbol74381$$MobileRTC

or:

Thread 1: EXC_BAD_ACCESS (code=1, address=0x22de42066fe8)
MobileRTC`___lldb_unnamed_symbol35648$$MobileRTC

Which iOS Client SDK version?

5.5.12509.0401

To Reproduce(If applicable)
Steps to reproduce the behavior:

  1. Get invited to a breakout room
  2. Get onHasAttendeeRightsNotification
  3. Call attendee.joinBO()
  4. After the BO view controller loads, call attendee?.leaveBO()
  5. Repeat steps #3 & #4 until crash

Hey @steven.otoole,

Thanks for using the dev forum!

Can you reproduce this one last time and obtain the SDK logs and crash log? They can be found be following the instructions at the bottom of this page https://marketplace.zoom.us/docs/sdk/native-sdks/iOS/mastering-zoom-sdk/sdk-initialization. Please email them to me at DeveloperSupport@zoom.us and include a link to this post.

Thanks!
Michael

Hey @steven.otoole,

Can you answer the following?

  1. Can it be reproduced in the sample project?
  2. Is it happening in Custom UI or Default UI?
  3. Are there any preconditions to reproduce this problem(e.g., attendees count and BO meeting count)?

Thanks!
Michael

Hi Michael –

Since your engineers were not able to reproduce this, I thought I would dig deeper into whether it could be our issue. It’s confusing to me because sometimes the crash is in your SDK code, but sometimes it’s in our code.

Thanks,
Steven

Hey @steven.otoole,

Interesting. I think we will need further info, please let me know what you find.

Thanks!
Michael
