Thanks for looking into this. Based on the fix, can you think of a (reasonable)
workaround that we can introduce to make things work with the versions of GCC
that exhibit the bug? 

The code is generated and I would consider changing the codegen if I can find a
workaround that doesn't (overly) pessimize optimization.
