--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This is riscv specific.
As the diagnostics explains, riscv_vector::vector_insn_info has non-trivial
default
constructor, so either it should be used only in {quick,safe}_grow_cleared and
not
{quick,safe}_grow vec operation, or should be changed not to have non-trivial
default constructor, because *_grow doesn't invoke the constructors, only
*_grow_cleared does.
