            Bug ID: 108679
           Summary: ice in modify_call, at ipa-param-manipulation.cc:656
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dcb314 at hotmail dot com
  Target Milestone: ---

For this C code:

struct S1 {
  signed f0;
};
struct S2 {
  struct S1 f2;
  short f8;
} g_18;
g_732, func_6_l_17;
static *func_12();
static func_6(struct S2 p_7) { func_12(func_6_l_17, p_7.f2, g_18, 0); }
*func_12(int, struct S1 p_14) {
  safe_lshift_func_int16_t_s_u();
  safe_unary_minus_func_uint64_t_u();
  g_732 = safe_mul_func_uint8_t_u_u(0, p_14);
}
main() {
  struct S2 l_10 = {3};
  func_6(l_10);
}

compiled by recent gcc, does this:

$ /home/dcb36/gcc/results/bin/gcc -w -O2 -ftrivial-auto-var-init=zero bug881.c 
during IPA pass: inline
bug881.c: In function ‘main’:
bug881.c:18:3: internal compiler error: in modify_call, at
ipa-param-manipulation.cc:656
   18 |   func_6(l_10);
      |   ^~~~~~~~~~~~

        ../../trunk.d1/gcc/ipa-param-manipulation.cc:656

The bug first seems to occur sometime between g:d0a3d55ae4a2656f
and g:1530a9b1f45a7ceb
