digitalmars.D.ldc - Error Message "ModuleInfo class is incorrect"

I'm trying to port the D Runtime, incrementally, to the ARM 
Cortex-M (thumb2) platform.  But after bringing object.d in, I'm 
getting this error message:

"object.d ModuleInfo class is incorrect"

Looking through LDC's source code, I found the following in 
toobj.cpp

// check for patch
else
{
#if DMDV2
	unsigned sizeof_ModuleInfo = 16 * PTRSIZE;
#else
	unsigned sizeof_ModuleInfo = 14 * PTRSIZE;
#endif
	if (sizeof_ModuleInfo != moduleinfo->structsize)
	{
	error("object.d ModuleInfo class is incorrect");
	fatal();
	}
}

I'm not sure if PTRSIZE is not properly defined for my platform, 
or if I need to make changes to ModuleInfo, or some other problem.

Please advise.

Thanks,
Mike

Are you sure you are looking at a LDC source file? 
driver/toobj.cpp does not contain this piece of code. The error 
message is produced in gen/module.cpp.

Did you change object.d_/object.di? Is the file really read? (use 
-v) If you could post a command line then I could try to figure 
out what is happening here.

Well, I sat down today and ran the same build script I wrote last 
night, and the error is gone.  I can't even figure out how to get 
it to reappear.  I must have done something stupid.

I'm sorry for the distraction.

You're welcome.

Are you aware of this issue? 
https://github.com/ldc-developers/ldc/issues/551

Maybe there is potential to join forces.
