Hey, please use the debug mode first and check the log to see if the instrumentation is working correctly before attempting to run afl-fuzz. See the readme for more details.
DynamoRIO itself has support for AArch64 since version 7.0 RC1 (see https://github.com/DynamoRIO/dynamorio/releases/tag/release_7_0_0_rc1). However, WinAFL client is only written with x86 and x64 in mind, and would need to be modified...
Might be that the target offset got changed when you recompiled test_gdiplus.exe. Try it against the prebuilt test_gdiplus.exe from bin64/.
I think it's a great idea :-)
I've seen this happen before but not with such frequency (it was a matter of days and not hours for me). Possibly it depends on the target, but I don't...
Can you see if it's any better with DynamoRIO 6.2.0-2?
Thanks for the info, that's good to know!
It shouldn't matter for WinAFL if the target module is loaded initially or during execution. WinAFL tracks module loads and wraps target method when the target module is loaded, regardless...
Thank you for reporting this! Given that I haven't been doing any computational geometry for a while now, any help in figuring out the root cause would be greatly appreciated....
FWIW I believe that polygons like this could be supported by adding a preprocessing step that would merge two polygons if they have a common node, but I never got...
