testcase-templated-method.cpp

Wrong (ccc is called with G<bool>, not G<CO>):
> $ nm testcase-templated-method.o | grep ccc | c++filt
>                  U void G<CO>::ccc<bool>(G const&<CO>)


Correct with c++filt from devel/binutils:
> $ nm testcase-templated-method.o | grep ccc | /usr/local/bin/c++filt
>                  U void G<CO>::ccc<bool>(G<bool> const&)

Correct with llbm's c++filt:
> $ nm testcase-templated-method.o | grep ccc | /usr/local/llvm10/bin/llvm-cxxfilt
>                  U void G<CO>::ccc<bool>(G<bool> const&)
