--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
It can't be part of libstdc++ though. Since you only compiled the module here:
```
"$homebrew_prefix/bin/g++-15" -Drsize_t=ssize_t -std=gnu++26 -fmodule-only
-fmodules-ts -x c++ -o std.bmi -c "$homebrew_prefix/include/c++/15/bits/std.cc"
```

So this sounds like an issue with how cmake handles std modules.

>If `std.o` is deferred to the consuming executable, that is a very leaky situation. 

I am not sure. this sounds more like a leaky in how cmake handles std modules.

Shouldn't the std module be handled as a seperate library rather than part of
the application/library that cmake is compiling?
