I just read in the man pages that pcre_free is a global variable and
points to free by default. In Pascal I'm loading it as an external
function, which the linker accepts but maybe it's not pointing to an
actual function and thus crashing? I'll have to ask some people who
are familiar with my Pascal compiler FPC but can you offer any advice
as to how it should be used? Thank you.

Btw, I also read that the pointer to be freed is a single block of
memory so I was able to use another function to call malloc's free
which seems to work just fine. Maybe it's not necessary I resolve this
the correct way?
