--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This is invalid code:
<source>:6:1: error: clones for 'target_clones' attribute cannot be created
6 | B::~B(){}
| ^
<source>:6:1: note: 'target_clones' cannot be combined with 'alias' attribute
<source>: In function '_ZN1BD0Ev.resolver':
<source>:6:9: sorry, unimplemented: virtual function multiversioning not
supported
6 | B::~B(){}
| ^
<source>:6:9: sorry, unimplemented: virtual function multiversioning not
supported
<source>:6:9: sorry, unimplemented: virtual function multiversioning not
supported
Note I notice clang accepts the code but emits completely wrong stuff.

With:
g++ pr104533.C -c -fPIC -Ofast -fno-semantic-interposition
it crashes since r12-2900-gfa28520fadb9405f. I can take a look.
