Disabling PDB/debug gen in Development configuration (Engine Source)

What do you mean by ‘fix it there’?

public override void SetUpConfigurationEnvironment(ReadOnlyTargetRules Target, CppCompileEnvironment GlobalCompileEnvironment, LinkEnvironment GlobalLinkEnvironment)
{
base.SetUpConfigurationEnvironment(Target, GlobalCompileEnvironment, GlobalLinkEnvironment);

		// NOTE: Even when debug info is turned off, we currently force the linker to generate debug info
		//       anyway on Visual C++ platforms.  This will cause a PDB file to be generated with symbols
		//       for most of the classes and function/method names, so that crashes still yield somewhat
		//       useful call stacks, even though compiler-generate debug info may be disabled.  This gives
		//       us much of the build-time savings of fully-disabled debug info, without giving up call
		//       data completely.
		GlobalLinkEnvironment.bCreateDebugInfo = true;
