[Bug tree-optimization/32366] New: [4.3 Regression] Segfault in significand_size with -ftree-optimize

["tbm at cyrius dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I'm getting the following segfault with current trunk.  This compiled
fine with trunk from 20070515 but produces the segfault with 20070604.

libsamplerate-termination_test.c: In function 'stream_test':
libsamplerate-termination_test.c:7: internal compiler error: Segmentation fault
Please submit a full bug report,

Testcase:


stream_test (void)
{
  static float input[20];
  int k;
  for (k = 0; k < 20; k++)
    input[k] = k * 1.0;
}
