PROGRAM ABORT : Unexpected result from pipe! expected 'P', instead received 'C' #179
Comments

According to the analysis of the winafl.c, if the ACCESS_VIOLATION exception occurs before the target_offset is executed, the log message like the above appears. Can I pass an exception to the application that occurred before target_offset was executed? |
The solution I chose is to pass the exception that occurred at the specified address to the application.
