[Qgis-developer] [gdal-dev] QGIS hanging when opening a FileGDB on 64 bit Linux

[Jeremy Palmer]

Wow Even - just amazing as always.

Have you confirmed that you can no open a FileGDB in QGIS? I still get the freeze when using GDAL trunk, but maybe that now a QGIS problem.

Jeremy,

I do think this is exactly the issue of http://forums.arcgis.com/threads/76527-CloseDatabase-hanging-on-64-bit-Lin ux- when-same-File-Geodatabase-opened-twice

At least I reproduced it on my own PC. I've implemented a workaround in GDAL trunk for that issue that implements ref-counting of the FileGDBAPI Geodabase handle at OGR side : http://trac.osgeo.org/gdal/changeset/26307.
