App Crashed loading shapefile #2982

Testing multiple apps that use the same base code. The base layer when compiled as an application loads the shapefile without any problem. I am using osgEarth 3.8 pulled last week. When I try to load the same shapefile using a managed C / C# to call the bases layer that was compile as a static library the apps crash with a null pointer in ogrspatialreference.cpp->OptionalLockGuard. The loader does not set a spatial reference so I donot see where that is coming from. The source code and the stack trace are shown below.

I have tried multiple shapefiles that do have a prj file with the same results. The stack trace does not seem to stem from the source code.

Other odd occurances that may or may not be related that have their separate loader
Geopackage files load and display in the base app but load without error but do not show
Postgresql data loads and displays in be base app but crash on the same error as shapefiles

Glenn Thanks for your reply. Unfortunately I seemed to take a major step backwards and cannot even getosgearth_viewer to run. Something seems to have changed in my build that I was unaware of. Regardless of the build mode I use, osg release dlls are called by osgearthd.dll according to depends.exe. Previous builds called the debug versions. My current crash when running osgearth_viewerd.exe is in spdlog Stack trace follows. KernelBase.dll!00007ffacf8c1b6a() Unknown vcruntime140.dll!00007ffa91365277() Unknown
