--- Comment #6 from Robin Dapp <rdapp at gcc dot gnu.org> ---
This happens when compiling opencv (commit
46dbc57a865594a5f9141a3a3b6878764df6cc0d as specified in PR119547) with GCC 15
and as Kito said, it's a regression.  IMHO this should be fixed.  clang seems
to have fixed it in the meanwhile?

My example is very similar:

#include <riscv_vector.h>

void
vsseg (float *a, vfloat32mf2_t b, vfloat32mf2_t c, unsigned long vl)
{
  vfloat32mf2x2_t foo = vfloat32mf2x2_t ();
}
