PoC showing unexpected __bdos results across inlines
Fixing this is needed for the Linux kernel to do much useful with alloc_size.
Most of the allocators are inline wrappers, for example.
This can be additionally shown to break __builtin_dynamic_object_size(), which
means all FORTIFY_SOURCE of alloc_size-marked inlines is broken. :(
