/* PR middle-end/98166: bogus -Wmismatched-dealloc on user-defined allocator
and inlining
Verify that without inlining, both the allocator and the deallocator
can be declared inline without a warning and that mismatched calls are
detected, but that declaring them always_inline does trigger a warning.
