Question

I’ve build my app to download a few zip-files with sizes from 10 up to 25 MB.
After download to the local documents folder I fire the ZKFileArchive method to unzip to that same folder.

In debug modus (device/simulator) all works fine. When I create a release which I install, the app crashes when it reaches

ZKFileArchive *archive = [ZKFileArchive archiveWithArchivePath:filePath];

With NSZombie enabled it throws me this:

  Thread 10 Crashed:

  5   libSystem.B.dylib                 0x32d197a4 0x32c9c000 + 513956

Could this be a memory issue? From times to times it throws me a level 1 memory warning, but as I’ve been reading this should not cause too much problems.

Any ideas?
Thanks in advance!

Answer 1

The framework you are linking looks like it was not built for the target platform. Illegal instruction means there is something very wrong with the binary.
