Sorry for the confusion. There was another issue which affected pcre2 only.
This was fixed in pcre1 as well:

I am not sure you can reproduce it with pcre1 test system, but there might be a
creative way to do it.
The problem is: you need to pass "\r\n\n" to pcre_exec, but with a buffer size
of 2, not 3. It is easy to do it in a C program, but the pcre1 jit test
infrastructure is unable to do it at the moment. I don't know whether it is
possible with pcretest.
Still there might be a way to do it without manipulating the buffer size, but I
didnm't have time to figure it out. It is a good regex challenge.
