--- Comment #2 from Jim Wilson <wilson at gcc dot gnu.org> ---
It is calling targetm.asan_shadow_offset which is a null function pointer
currently for RISC-V.  This is related to Kito's recent patch to re-enable =
ksan
support when asan_shadow_offset isn't defined.  But it looks like there are
multiple params that can cause asan_shadow_offset to be called for ksan whe=
n it
normally isn't.  So this change may need to be removed.

Good news is that we have a patch to add asan support for RISC-V which would
make Kito's toplev.c patch unnecessary for us.=
