--- Comment #3 from JuzheZhong <juzhe.zhong at rivai dot ai> ---
I see. I didn't reproduce the ICE since I didn't enable gcc_assert_checking.

Could you tell me how to enable it ?


I hack the codes as follows:

diff --git a/gcc/poly-int.h b/gcc/poly-int.h
index 828714ee910..24cce294414 100644
--- a/gcc/poly-int.h
+++ b/gcc/poly-int.h
@@ -1825,7 +1825,7 @@ template<unsigned int N, typename Ca, typename Cb>
 inline poly_int<N, Ca>
 force_align_down_and_div (const poly_int<N, Ca> &value, Cb align)
 {
-  gcc_checking_assert (can_align_p (value, align));
+  gcc_assert (can_align_p (value, align));

   poly_int<N, Ca> r;
   POLY_SET_COEFF (Ca, r, 0, ((value.coeffs[0]


Then I can see the assertion FAIL.=
