Description
The following query leads to a segfault in PostGIS (using 1.5.8 on Postgres 9.1): SELECT box(Envelope(Transform(GeomFromText('GEOMETRYCOLLECTION EMPTY',4326),4326)));
The stacktrace of the core dump is as follows: (gdb) bt #0 0x00007f303e80edf0 in box3d_to_box_p () from /usr/lib/postgresql/9.1/lib/postgis-1.5.so #1 0x00007f303e808e2b in LWGEOM_to_BOX () from /usr/lib/postgresql/9.1/lib/postgis-1.5.so #2 0x0000000000576505 in ??

Confirmed, crashes 1.5 on OSX. Does not crash 2.0, so the future is safe.
