Crash: CaptureSDK block_destroy_helper

[ghost]

Hi,

Please see stack trace for crash experienced using CaptureSDK 1.4.51. Can this be addressed in an upcoming release?

Hi @michael-ps,

can you try the latest version please? The 1.5.7: https://github.com/SocketMobile/cocoapods-capturesdk/releases/tag/1.5.7

Hi @cyrille-socket,

Thanks for your response. Was there a fix applied for this issue since version 1.4.51? Updating the SDK is expensive for us as it requires a full regression testing cycle.

Hi @michael-ps,

following your stack trace it's a bit difficult to say what is the cause of the crash. I understand that you have some tests to run again but it's the only way to know. We constantly improve our SDK with small bug fixes and improvements so it might be fixe in the next versions following yours.

Also, can you provide the code where you use the SDK with the commands that you send to the device? Which device you use? Which iOS version?

Thank you

Hi @cyrille-socket,

I got the same stack trace here, and we're using the s700 device with the SDK version 1.5.9 in the app, which happened from iOS 15 to 16.

Would you please check if the following stacks I provided will be fixed on the latest version?

Thank you.
