Confirmed. Introduced by r15-4601-ge2e798b8607401.
which transforms trunc_div into exact_div.

gimple-lower-bitint.cc does not expect EXACT_DIV_EXPR, it only handles:
      case MULT_EXPR:
      case TRUNC_DIV_EXPR:
      case TRUNC_MOD_EXPR:

lower_muldiv_stmt also does not handle EXACT_DIV_EXPR.

I suspect we can handle EXACT_DIV_EXPR the same as TRUNC_DIV_EXPR .
