Now that you have a minimized program, check if the crash still reproduces with `./syz-execprog -threaded=0 -collide=0` flags. If not, then you will need to do some additional work later.
Now, run `syz-prog2c` tool on the program. It will give you executable C source. If the crash reproduces with -threaded/collide=0 flags, then this C program should cause the crash as well.

If the crash id not reproducible with -threaded/collide=0 flags, then you need this last step. You can think of threaded/collide mode as if each syscall is executed in its own thread. To mode such execution mode, move individual syscalls into separate threads. You can see an example here: https://groups.google.com/d/msg/syzkaller/fHZ42YrQM-Y/Z4Xf-BbUDgAJ.

This process is automated to some degree in the `syz-repro` utility. You need to give it your manager config and a crash report file:
