Problems in the application of driller

[PayneLin]

Dear Sir, I am very glad to use your Driller tool to do fuzzing test. However, when I use driller in the applications such as libtiff, w3m, nasm, libjpg-turbo and so on, the Symbolic Execution tool Angr will report some erro. Therefore, May you tell me whether there are some good application or binaries can be well tested by driller. Thank you!
