TFE_DeleteContext stuck on exit when loading from dll

[mwindowshz]

on exit my app is stuck on inline

context::~context() {
        TFE_DeleteContext(this->tfe_context);
    }

I have a dll that loads cppflow model, , runs and on exit, the code jumps to this contex destructor, but It does not close and stays stuck on TFE_DeleteContext()
why is this. do I need to call some release function?

The issue is that Contex class creates one global contex, and it is freed on the end. but when loading a the cppflow in a dll, My class usese cppflow, and I delete my class object this does not free the global contex.
The hint for solution came from here:

cppflow/include/cppflow/context.h

Lines 43 to 49 in e389df0

	// TODO: create ContextManager class if needed
	// Set new context, thread unsafe, must be called at the beginning.
	// TFE_ContextOptions* tfe_opts = ...
	// cppflow::get_global_context() = cppflow::context(tfe_opts);
	inline context& get_global_context() {
	static context global_context;
	return global_context;

Problem with multi threaded,
Our solution was to create contex and save it, then release it manualy on exit, and removing the ~() destructor call to TFE_DeleteContext(this->tfe_context);

our class creates
TFE_Context*_contextInference = nullptr; in constructor:

// see comments cppflow/context.h linse 44 and 88
MyClass:MyClass()
{
    TFE_ContextOptions* tfe_opts = nullptr;
    cppflow::get_global_context() = cppflow::context(tfe_opts);
    _contextInference = cppflow::context::get_context();
}
MyClass~MyClass()
{
   TFE_DeleteContext(_contextInference);
  _contextInference = nullptr;
}
