However it sometimes get this wrong, so you have to override it
and tell it to emit them all anyway and let the linker do the
eliding instead.
This is a known problem of all the compilers since its done by
the shared frontend, rather than the glue layer.
It is a bug, but given how complex and time consuming it can be
to minimize it to a small reproducible example, its not always
worth the time to try and report it.
Thanks again for your lucid explanation. I will save
`-fall-instantiations` flag in my main memory.
