gcc9-pr88701.patch

For what I wanted to achieve with that change (i.e. put the compound literal
decls in the block scope they belong to), the following works too; it is fine
if the compound literals in the function parameters are handled as before - in
the scope of the function.

Does not appear with GCC 8 branch, so a regression, can someone bisect to find
what commit introduced this ICE?
