Empty monitor folder in php target

[harrison4ride]

Hi,

I tried to run the experiment of aflplusplus, fairfuzz, moptafl, hongfuzz on PHP, and I found only exif has monitor information while others are empty.

Here is the current log in hongfuzz on PHP json:

Do you have any clue why this will happen? I am using your script on magma V1.2.

From the logs it looks like the fuzzer ran correctly. So it could just be the bugs were never reached (and subsequently, never triggered).
