[QGIS-Developer] [gdal-dev] QGIS from OSGeo4W crashes with latest update on NetCDF

[Joaquim Manuel Freire Luís]

But I do find something strange in that nc file. Mirone (Matlab independent nc loader) errors when trying to load it because of the  “Conventions” attribute and HDF-Explorer says it’s a “4-byte null-terminated ASCII string” when in fact that attribute has 6-bytes
“CF-1.5”

Pedro,

Probably a netcdf lib related issue. I have a very fresh GDAL build (from yesterday’s master) and can access that file. Either from GDAL or GMT, but my nc lib has not been updated for some time (which is not so bad as nc has had a couple of issues in recent past).

Hi all,

Sorry about the cross posting but today, after the update of OSGeo4W to qgis-dev 3.15.0-82, I get a QGIS crash both with qgis-dev, qgis-ltr-dev 3.10.10-3 and qgis-rel-dev 3.14.16-3.

I've only looked at Desktop updates and so I cannot say what libs were updated at the same time.

The crash happens when I try to open some NetCDF file (for instance http://mf2.ipma.pt/downloads/?latest=arome.2m.relative_humidity&region=PT2 ) as raster file, as mesh layer or simply when I open a folder with a NetCDF file inside Browser.

This is something like this one: https://issues.qgis.org/issues/21162

As it only happens with QGIS "-dev" versions, I believe it can be related with GDAL 3.2.0dev, but I cannot say what version I had before this update, maybe from one week or two ago.

Can someone reproduce?

Another issue with QGIS "-dev" versions is related to GRASS. I get this error message on QGIS initialization, and then I cannot, for instance, create a new mapset with GRASS Plugin:


GRASS init error: Problem in GRASS initialization, GRASS provider and plugin will not work : Module built against version 8bcecc9a6 but trying to use version d8fbd49af. You need to rebuild GRASS GIS or untangle multiple installations.



I can open two different tickets, but I'm not certain about the right place to open them.



Thanks!



Best regards,

Pedro Venâncio
