hello,admin ,there is a issues when i use winafl-cmin.py, my script is : >C:\Users\X\AppData\Local\Python27\python.exe winafl-cmin.py --working-dir C:\Users\X\Desktop\winafl\build64\bin\Debug -D C:\Users\X\AppData\Local\DynamoRIO-Windows-10.0.19672\bin64 -t 100000 -i C:\Users\X\Desktop\winafl\testcases\corps-objs -o C:\Users\X\Desktop\winafl\testcases\corps-objs-simplify -coverage_module test.exe -target_module test.exe -target_method main -nargs 2 -- test.exe @@

so my DynamoRIO version: 10.0.19672 fuzzed target: x64 winafl build arch:x64 with intel pt, (git submodule update -- init --recursive) windows version: win10 22h2 19045.3086 the output log is : corpus minimization tool for WinAFL by [email protected] Based on WinAFL by [email protected] Based on AFL by [email protected] [+] CWD changed to C:\Users\X\Desktop\winafl\build64\bin\Debug.

[-] PROGRAM ABORT : Unexpected result from pipe! expected 'P', instead received ''

     Location : run_target(), C:\Users\X\Desktop\winafl\afl-showmap.c:715

the issue occur immediately before i can see the fuzzing static information

and what's more, if I fuzz it directly ,it will show: C:\Users\X\Desktop\winafl\build64\bin\Debug\afl-fuzz.exe -i C:\Users\X\Desktop\winafl\testcases\corps-objs -o -debug .\output\fuzzobj -D C:\Users\X\AppData\Local\DynamoRIO-Windows-10.0.19672\bin64 -t 200000 -- -coverage_module test.exe -fuzz_iterations 5000 -target_module test.exe -target_method main -nargs 2 -- test.exe @@ WinAFL 1.16 by [email protected] Based on AFL 2.43b by [email protected] [+] You have 12 CPU cores and 0 runnable tasks (utilization: 0%).

and then, it will stuck at [*] Attempting dry run with 'id_000000'... until timeout occur. and i can't see any debug log,,

can you give some hint? i stuck at here for a long time
