Sadly, the syzkaller characterized it as a non-reproducible bug and there were empty
 repro files. But if manually executing in VM like this ?./syz-execprog -executor=
./syz-executor -repeat=0 -procs=16 -cover=0 crash-log?, it crashed when executing exactly 
program 1056 using log0 provided.

I failed to generate the C reproducer with syz-repro as it said ?no target compiler?
in the final step. I would appreciate if you could give some hints.

syz-repro should produce a smaller syzkaller log before it tries to
generate a C file.

I use:

$ syz-repro -config qemu.cfg logN

... and in most cases it will eventually print a smaller log to the
console.

Thanks,
