[thomas-chris]

Having installed version 7.4.3 via SPM our app randomly crashes with the error

malloc: *** error for object 0x11: pointer being freed was not allocated

Description

Having installed version 7.4.3 via SPM our app randomly crashes with the error

malloc: *** error for object 0x11: pointer being freed was not allocated

Steps to Reproduce

There are no specific steps, as the crash is not occuring all the time, sometimes it happens on start up, other times while browsing the app.

Expected Behavior

The app doesn't crash

Relevant Logs / Console output

malloc: *** error for object 0x11: pointer being freed was not allocated## Your Environment

iOS 16.2, xcode 14.2.0

Additional context

We are not 100% sure that New Relic pod is solely to blame, but downgrading to 7.4.0 seems to have stopped the crash occuring

Same issue here - the crash started only in the version which contained a bump from 7.4.0 to 7.4.3 if that helps

crash_info_entry_1 are all like

home24(697,0x2a85b7000) malloc: *** error for object 0x280fccc90: pointer being freed was not allocated

[Mordil]

Still seeing this in 7.4.4

We're rolling back to 7.4.0

Please use the latest New Relic iOS agent 7.4.11 which contains a new feature flag, NRFeatureFlag_NewEventSystem. Enable this feature flag which should remove the ~Payload() crash.
