--- Comment #7 from Patrick Palka <ppalka at gcc dot gnu.org> ---
Probably related:

void f() {
  [[gnu::used, gnu::section(".test")]] static int p;
}

inline void g() {
  [[gnu::used, gnu::section(".test")]] static int p;
}

int main() {
  f();
  g();
}

is rejected with

<stdin>:6:51: error: ‘p’ causes a section type conflict with ‘p’
<stdin>:2:51: note: ‘p’ was declared here

Jason hinted at a solution back in 2019:
