--- Comment #1 from Alexandre Oliva <aoliva at gcc dot gnu.org> ---
The ICE is fixed with the incremental patch in the git branch aoliva/pr64164. 
I had to introduce code to copy the incoming byref param to the location
assigned by out-of-SSA for the partition holding the default (incoming) SSA
version of the parameter.  I have only inspected the generated code visually to
tell whether the generated code did what I meant it to do, so I'd appreciate
some execution testing too.  John, if you can help with that, would you like
the asm for this one testcase, or is it easy enough for you to give the branch
a round of testing?  Thanks,
