Hello dev list,
I’m using GDAL 2.1.2 in an iOS app (statically linked). When executing
OGR_L_SetFeature() it usually works fine, but randomly crashes with
EXC_BAD_ACCESS.
The crash is in sqlite3 and appears to be due to dereferencing a NULL pointer,
as far as I can tell from the back trace.
In my app, the crash occurs when I call, "OGR_L_SetFeature(layer, feature)”, at
which point both “layer” and “feature” are non-NULL, and the layer is in a
GeoPackage data source.
The top of the back trace is:
MyApp`sqlite3_clear_bindings(pStmt=0x0000000000000000) + 24 at sqlite3.c:75797,
queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1,
address=0x0)

syncToDisk](self=0x000000017422cd00, _cmd="syncToDisk") + 92 at
VectorFeature.m:56
I don’t know enough about the SQLite or GeoPackage code to make any sensible
progress on this. Can somebody please point me in the right direction to
figure out what I’m doing wrong?
Cheers,
Nik.
