Actually it looks like I might be wrong in the end.

For the reduced testcase in comment #1 we have:
  int __trans_tmp_5;
  long long int g_263.0_1;
  int func_16_l_1358.1_2;
  _Bool _4;

  <bb 2> [local count: 1073741824]:
  g_263.0_1 = g_263;
  _4 = g_263.0_1 == 357942;
  __trans_tmp_5_6 = _4 ? 357942 : 357941;


In this case, 357942 are 2 different modes (SImode and DImode).

Still causes by r14-2667-gceae1400cf24f329393e96dd9720 .
