Thank you for the awesome project!

I'm having a hard time fuzzing the 32 bit-program,
so I just wonder when will this rework be done?

Hey @donghyunlee00,

Not quite sure about the 'when' so I would recommend to grep for 32b and go through the closed issues; it should give you enough background to get started :)

Cheers
