No, I didn't. I've tested with the OGR API that it solved the issue with the following access pattern : ds1 = ogr.Open(datasetname) ds2 = ogr.Open(datasetname) ds2 = None ds1 = None > I still get the > freeze when using GDAL trunk, but maybe that now a QGIS problem. Just to be sure that you are using the version with the fix, if you break with gdb when it hangs, does it display FGdbDriver::Release() in the stack trace ? > > -----Original Message----- > From: Even Rouault [mailto:even.roua...@mines-paris.org] > Sent: Tuesday, 13 August 2013 11:29 a.m. > To: gdal-...@lists.osgeo.org > Cc: Jeremy Palmer; 'qgis-developer@lists.osgeo.org' > Subject: Re: [gdal-dev] QGIS hanging when opening a FileGDB on 64 bit Linux > > Le lundi 12 août 2013 22:12:11, Jeremy Palmer a écrit : > > Further to this I see that when you open a FIleGDB in QGIS 3 OGROpen > > calls made to the same database before any OGR_DS_Destroy calls are > > made.
