Hi everybody. I hope somebody could help me with this "leaks" report from FastMM4.. I have no idea what BaseThreadInitThunk and similar mean.. --------------------------------2024/6/27 17:52:48-------------------------------- A memory block has been leaked. The size is: 20 This block was allocated by thread 0x38E4, and the stack trace (return addresses) at the time was: C775C2 [System.pas][System][@GetMem$qqri][4962] C7C6F8 [System.pas][System][@StartExe$qqrp23System.PackageInfoTablep17System.TLibModule][24306] 75F2FCC9 [BaseThreadInitThunk] 77AD7CBE [RtlGetAppContainerNamedObjectPath] 77AD7C8E [RtlGetAppContainerNamedObjectPath] The block is currently used for an object of class: IdThreadSafe.TIdThreadSafeInteger The allocation number is: 7395 --------------------------------2024/6/27 17:52:48-------------------------------- A memory block has been leaked.

Setup is delphi 10.4.2 - xcode 13 - sdk 15 I was finaly able to get instruments to work on my IOS app. (Had to build using developer cert and profile not adHoc) Where I run my app, with Leaks this is what I see for a short timestamp. My question is are all these leaks? How do I relate this to my code? In several cases, the program is just sitting on a screen waiting for user input, but the leak list keep growing. There are no timers in my program.
