Hi team!

I'm having an issue trying to minify my corpus with winafl_cmin.py (WinAfl compiled with DRIO 9.0.1). The script just stuck at: [*] Testing the target binary

Any ideas of why this could be happening?

Hi, in order to have some idea what's going on, could you

share your debug log (from running in -debug mode, as described in the documentation), together with the command line you used to run it.
post the command line you are using for afl-fuzz.exe.

check application bit depth: cd C:\Program Files (x86)\7-Zip 7z.exe l [target application] | findstr CPU

If you did everything right, try to recompile WinAFL and DinamoRIO on computer where you are doing the minimization
