Oh When I record app(Mali-G77 MC9)，app aways is crash（Memory Crash about libc） I note recording log: Note: By default to support multi-platform playback we override api alignment values to our recommended values. To disable this set the align recommended option to false How to disable the align ? Do you have recommended config? ---

Hello, Thank you for sharing the details. > How to disable the align ? We don’t think the alignment changes would cause any issue here. It could mostly be only a problem at record time if the application is already close to the memory limits of the phone and the changes push it over or could be an application issue and it doesn’t correctly handle different alignments. You could still give it a try while following the instructions as given in the documentation below, [https://docs.imgtec.com/tools-manuals/pvrcarbon-manual/topics/pvrcarbon-recorder/configuration/environment-variables.html](https://docs.imgtec.com/tools-manuals/pvrcarbon-manual/topics/pvrcarbon-recorder/configuration/environment-variables.html) Also, for us to be better diagnose your issue it would be helpful if you could share the carbon recording with the problematic frame captured and a full logcat from the Mali-G77 MC9 device. Kindly register and raise a ticket in our support portal while adding these attachments, [PowerVR Insider Support] [[https://pvrsupport.imgtec.com](https://pvrsupport.imgtec.com/)] ([https://pvrsupport.imgtec.com/](https://pvrsupport.imgtec.com/)). > Do you have recommended config? As for recommended config, In most cases what carbon sets up by default should be good enough. Best Regards, Nagnath ---

Hello, From the logcat, we found that the recorder has encountered a SIGSEGV (Segmentation fault) right after the device creation is done and then it fails to capture further calls which looks like are related to vulkan initialisation and setup. It looks like the recording wasn’t so successful in the first place. And for the carbon recording, when tried to replay it on our android device, as the initial set of calls were failed to be recorded as seen above, it throws “Missing call” error for first set of calls. We would like to know, 1. If the application runs fine when you launch it on your device otherwise? 2. Did you try while disabling the API alignment and try recording again? 3. Will it be possible for you to share the apk with us to see if the app runs fine and if we are able to record it fine on our device. Best Regards, Nagnath
