I already Tried with:
-generate_unwind
-patch_return_addresses
from jackalope.
Of course, after the target process dies, the program is start again, but the program I'm targeting should be Loopable because the initial initial process takes too long.

Hi, could you share the output you're getting from Jackalope?
Does the test program work correctly for you:
fuzzer.exe -in in -out out -t 1000 -delivery shmem -instrument_module test.exe -target_module test.exe -target_method fuzz -nargs 1 -iterations 10000 -persist -loop -cmp_coverage -- test.exe -m @@

YES. I got everything ok with other things(original test.cpp) but, my harness's DLL make some Exception(C++ EH exception, in normal situation, it will be handle by program's handler) but It handle by Jackalope and Program died so I cant loop.
And I can't understand what do you mean for "output from jackalope"
from jackalope.
By "output from jackalope", I mean what Jackalope prints.
It's difficult to diagnose the issue without knowing more about your target, but if it was due to C++ exceptions, then -generate_unwind
or patch_return_addresses
should have fixed it. One other thing you can try is -stack_offset 1024
.

Jackalope doesn't export any error messages. But, EXEC/s is zero, and only runs(exec increase) once every 10 seconds. (I can infer that it runs once and the process dies because the time for the first initialization is about 10 seconds, and when I look at it in Process Explorer, it's actually dying.) I'll try additional solutions and let you know the results right away.
