Diego, your analysis is exactly correct about what is happenning.

I agree, in principle.  The C++ FE should not set TREE_READONLY on 
variables that require dynanmic initialization.  Until now, that's not 
been a problem, and it does result in better code.  But, it's now 
becoming a problem, and we have others way to get good code coming down 
the pipe.

I do think the C++ FE needs fixing before Diego's change gets merged, 
though.  I can make the change, but not instantly.  If someone files a 
PR, and assigns to me, I'll get to it at some not-too-distant point.
