#132 closed defect (fixed)

CAPI GEOSEqualsExact() segfaults comparing POINTs

Reported by: hrz@… Owned by: strk@…
Priority: critical Milestone:

Severity: Significant Keywords: imported, phpbugtracker

Description (last modified by mloskot)

To be exact, it segfaults when one of the points is empty. I.e., the following code fails: 

 geom = GEOSGeomFromWKT("POINT(44 32.2)");
 geom2 = GEOSGeomFromWKT("POINT EMPTY");
 GEOSEqualsExact(geom, geom2, 0);

A backtrace looks like: 

#0  geos::geom::Geometry::equal (this=0x80f91d8, a=@0x0, b=@0x80fd6b0, tolerance=0) at Coordinate.inl:80
#1  0xb7aebe84 in geos::geom::Point::equalsExact (this=0x80f91d8, other=0x80f0fd8, tolerance=0) at Point.cpp:200
#2  0xb7ba80d3 in GEOSEqualsExact (g1=0x80f91d8, g2=0x80f0fd8, tolerance=0) at geos_c.cpp:414

System details are the same as reported in bug #126
