[Bug Report] Inquiring about GNU Patch program bug report

Dear whom it may concern,

Hello, this is Jaehyeok Lee, and I'm the master program student in Sungkyunkwan University from South Korea.

While doing my paperwork, I just found the bug command in the program "Patch". That's why I would like to send this mail to confirm if this bug is already reported correctly. The bug command is as follows:

"./patch" "--deb" "0" "\x01\x01" "\n" 
 
We found this command through symbolic execution testing by utilizing the widely-used tool KLEE, and \x01 stands for the ASCII character of 1 with hexademic form inside the command.

However, it's gonna be challenging to execute a patch program with ASCII characters as it is, since we just tried to execute all commands with binary form in KLEE-replay program with test case generated from KLEE. (We just learned about this command form from the test cases generated by the KLEE.)

Thank you!
