[pgpool-general: 35] Re: ERROR: *** glibc detected *** /opt/pgpool/bin/pgpool: malloc(): memory corruption: 0x091aad88 ***

[Tatsuo Ishii]

I found a nasty bug with black/white function list memory allocation
logic.  While etracting each function taken, it adds "^" and "$" if it
does not include them.  Problem is, someone forgot to add extra space
for them. Included is a one line patch to fix the problem. Please try.
