[pcre-dev] pcre_free crash

I just compiled the static library on an Intel Mac running OS 10.5.8
and calling pcre_free is crashing (from GDB: Program received signal
EXC_BAD_ACCESS, Could not access memory). I'm accessing the library
from a Pascal interface I translated but I suspect that's not the
problem as the other functions I'm using are working.

Is this a known bug on my system? Thank you for any ideas.
