[Bug tree-optimization/71206] [7 Regression] ICE on valid code at all optimization levels in both 32-bit and 64-bit modes on x86_64-linux-gnu. (verify_gimple failed)

--- Comment #4 from Marc Glisse <glisse at gcc dot gnu.org> ---
I am starting a bootstrap+regtest with:

 /* (X ^ Y) ^ (X ^ Z) -> Y ^ Z  */
 (simplify
  (bit_xor (convert1? (bit_xor:c @0 @1)) (convert2? (bit_xor:c @0 @2)))
  (if (tree_nop_conversion_p (type, TREE_TYPE (@1))
       && tree_nop_conversion_p (type, TREE_TYPE (@2)))
-  (convert (bit_xor @1 @2))))
+  (bit_xor (convert @1) (convert @2))))
