Why does Cinema not load a plugin file with a String variable in the global scope? This is very
annoying.

#include <c4d.h>
  
String g_string;
  
Bool PluginStart() {
	return TRUE;
}
  
// ...

Because the C4D OS pointer isn't valid before reaching PluginStart. Unfortunately non POD datatypes (http://www.cplusplus.com/reference/type_traits/is_pod/) need to allocate memory and for static global variables the compiler will try create them before you've reached PluginStart.

Best regards,

The first question is why do you need global C4D::String ?

Because C4DOS is NULL at the time global variables are initialized it is not possible without a change / hack on C4D::String class.

I don't need this in one of my plugins, but I needed it for a quick test. I used a pointer instead
and was even too lazy to free it in PluginEnd().
