CreateProcess failed GLE =2 and drrun.exe with -debug reports nothing
I am trying run winafl on a Delphi 32bit executable, but afl-fuzz fails with a GLE=2 and no further details
S:\winafl\bin32>afl-fuzz -i input -o output -t 1000 -D s:\DynamicRIO\bin32\ -- -coverage-module dwsFuzz.exe -target_module dwsFuzz.exe -target_method FuzzTest -nargs 1 -- s:\winafl\bin32\dwsFuzz.exe "@@"

[-] PROGRAM ABORT : CreateProcess failed, GLE=2.
Location : create_target_process(), c:\work\winafl\source\afl-fuzz.c:2330
(I tried the @@ with and without simple and double quotes)
when attempting a debug run with drrun.exe, no log file is created and no error is reported, the command
S:\winafl\bin32>\DynamoRIO\bin32\drrun.exe -c winafl.dll -debug -target_module dwsFuzz.exe -fuzz_iterations 10 -target_offset 0x002EFBE4 -nargs 1 -- s:\winafl\bin32\dwsFuzz.exe s:\winafl\bin32\input\test.pas
Just returns with an empty line.
I also tried -target_method with the method name (I checked it is properly exported with Nirsoft DLL export viewer), but no difference.
Any hints as to what is missing ?
GLE means "GetLastError", so GLE=2 indicates ERROR_FILE_NOT_FOUND so, please be sure that s:\winafl\bin32\dwsFuzz.exe and DynamoRIO files exist.
