[GRASS-user] Error in r.in.gdal: CPLCalloc(): Out of memory allocating for "EHdr/ESRI .hdr Labelled" driver

Frank,

Thanks for the feedback. The error persists with gdalinfo -mm:

Filing a bug in the gdal bugtracker.

Eric,

This isn't a big raster, so that's not the problem.  Can you try
"gdalinfo -mm" on the same file?  Negative allocation errors normally
mean a bug somewhere in the driver code.  If gdalinfo -mm also has
a similar error, then file a bug against GDAL and ensure you include
the .flt header (the data itself should not be needed).

Best regards,
