We have recently implemented a geo raster importer, and all seems fine,
except that we hit an issue with a particular GRIB2 file from the NOAA
website, where we get an inconsistent crash inside GDAL after a few hundred
scanlines.
We have seen two different crashes inside GDAL, and a third in one of our
code paths, but given that there is a memory corruption, the latter is
perhaps unsurprising.
All crashes report "double free or corruption (fasttop)".
We only get the crash occasionally, and have only been able to trap it in
the Debugger a couple of times, with nothing obviously wrong.
Here is a link to the GRIB2 file in question:

Is running under valgrind an option ?
