[gdal-dev] EXC_BAD_ACCESS on 1.11 OGROpen() SQLite or GeoPackage

[Nik Sands]

Please ignore this one (below).  Sorry for wasting the list's time on this one.  I can now build GDAL 2.x for iOS no trouble, and I do not get the crash with GDAL 2.1.2.

(After not being able to get GDAL 2.x to build for iOS last October, I gave up on it and went back to 1.11.  I’ve just tried 2.1.2 and it built first time, no trouble, just using the same build script that I’d been using for 1.11.  I do not know if it is my build script that has changed since October, or if 2.1.2 fixed something that was causing me problems.  I can’t recall what the issue was back then.)
