vector operations crash in 64bit OSX

Reported by: kyngchaos Owned by: grass-dev@…

CPU: x86-64 Platform: MacOSX

Description

Some vector operations crash on OSX 64bit. This is in both 6.x SVN and 7.0 trunk.

One case is on import, when v.in.ogr gets to the Break Polygons step. There are probably other places where it could happen, since it crashes in the rtree library. OSX crash trace (trunk):

I tried at one time to debug it in Xcode, but it didn't make sense to me, and I don't know much about debugging to know what to look for. Some explicit GDB commands to use, and I could try from a terminal...
