I have a shapefile which makes ogrinfo segfault, python segfaults with the following errors upon trying use ogr module with it:

I have been unable to reproduce a problem with ogr trunk. Tested on windows, and on 32bit linux (built from source) under valgrind.

What version are you using?

Things I tried included: 

  valgrind ogrinfo -al hydrotop.shp > /dev/null
