Please file a ticket, ideally with a dataset to reproduce

Say you have a file called raster.vrt. In that file are 15 tif's. 9 of
those rasters don't have data (nodata) at the specified lon/lat:
gdallocationinfo -geoloc -valonly -field_sep "," rasters.vrt
-88.730767 32.649060
The above may return 6 values, with or without -field_sep:
26,2,2,0,3.10467481613159,32.7341842651367,1433
You have no idea which tif those values belong to. In versions 3.9.2
or earlier, it returns the 'nodata' value for each tif. Not only is
nodata a valid value, it acts as a place holder. 15 rasters, 15 values
returned.
Yes, you can remove the -valonly switch and use -xml, but then it
becomes a parsing debacle. Unnecessary code and overhead.
Apologies for being a pain. I just rolled 3.11.1 and now 3.11.2 into
production, up from 3.9.2 and it's breaking stuff I did not
anticipate. :)
Thank you!
Scott
