Issue 54: segfault with st_numgeometries when --enable-debug
http://code.google.com/p/postgis/issues/detail?id=54

Comment #4 by pwramsey3:
It's actually worse... now running st_area also causes a segfault.

(gdb) run --single postgis
Starting program: /usr/local/pgsql/8.3/bin/postgres --single postgis

PostgreSQL stand-alone backend 8.3.3
backend> select st_area(the_geom) from va limit 1;
          1: st_area     (typeid = 701, len = 8, typmod = -1, byval = f)
         ----

Program received signal SIGSEGV, Segmentation fault.
