Here is how I debug APP with malloc stack history on idevice, it’s really complicate, but I have no other way to deal with an auto release pool memory problem.
You need A jailbreak idevice with developer tools installed, then you have gdb.
To enable malloc stack loggin, you need set environment variables MallocStackLoggingNoCompact and MallocStackLogging, we need some trick to do it.
First, we need grant your app root privilege.
mv -f /User/Application/xxxxxxxxxxxxx/YOUR_APP.app /Application/YOUR_APP.app
chown -R root:wheel YOUR_APP.app
chmod 4755 YOUR_APP.app/YOUR_APP
Rename your program
mv YOUR_APP.app/YOUR_APP YOUR_APP.app/BACK_UP_NAME
Use a short shell scrip to start your program, so we can keep the env. Save it to YOUR_APP.app/YOUR_APP
Just start you app, touching on the icon or use open command, you’ll see a stack log file in /tmp
ps aux | grep YOUR_APP find process id,
gdb -p PROCESS_ID attach to the progress, make a breakpoint, try
info malloc ADDRESS, malloc history will show up.
