XYZ regression - "too many stepY values" erroneous failure
|Reported by:||shot2||Owned by:||warmerdam|
Bug observed with GDAL 2.1.0beta1 Win32 (from Gisinternals) and SVN-trunk Linux-amd64.
When reading a valid XYZ dataset (see attached minimal example: regularly-spaced X and Y values as float, none missing) various raster utilities e.g. gdalinfo fail with the error message
ERROR 1: Ungridded dataset: At line 10, too many stepY values
This error was not present in the 1.10.x (Ubuntu 14.04) and 1.11.x (GisInternals) releases.
As far as I can tell, it might be related to the introduction of a new stringent StepY=0 test at some point around rev 27401-27409 of xyzdataset.cpp.
