Hi, i am sorry for the late response. I tried to reproduce this issue but failed. Does it still occur with 7.4.2?

After some investigation and checks i would judge, that this is an PHP issue. In PHP 7.1 was an issue like this based on strange chars in the stream, which also let to segfaults. I would suggest that you wrote a PHP issue if the issue still persists.

Yes, it still occur with 7.4.2:
