python-grib doesn't work on 64 bit system

[Paul Tomblin]

Installed "python-grib" package. Downloaded GRIB2 files from the NOAA. Ran a simple program that should read the header information in the grib file:

rom ncepgrib2 import Grib2Decode
import sys

args = sys.argv[1:]
for arg in args:
    print arg
    print Grib2Decode(arg, False)

And the program kills the python interpreter:
python foo.py gfs.t06z.pgrb2.2p50.f105
gfs.t06z.pgrb2.2p50.f105
*** Error in `python': free(): corrupted unsorted chunks: 0x00000000023c0c60 ***
Aborted (core dumped)

Tried this with several GRIB2 files and got the same results. Copied the python program and the GRIB2 files to a system that runs 32 bit Debian on a 64 bit kernel, and the program worked fine.
