[Bug tree-optimization/21293] New: ICE on valid

[dalej at gcc dot gnu dot org]

The following crashes at compile time with -O2, on a local compiler built from 4.0 branch sources:
foo3.c: In function 'gciprt_':
foo3.c:8: internal compiler error: in set_value_handle, at tree-vn.c:179
(This has been cut down from a large original which did not have all those uninitialized variables.)

struct {
int k_;
} detwfn_;
struct {
double x_[1];
} fmcom_;
void gciprt_(int *iw_)
{
int Tmp8, ibcon_, iwrk_, ibo_, jstsym_, lcivec_, iacon_, igmul_;
int i_, nsym_, ipica_, ipicb_;
ibo_ = iwrk_ + 43;
Tmp8 = detwfn_.k_;
for(i_ = 1;i_ <= Tmp8;i_++) {
  gcisym_(iw_,&fmcom_.x_[lcivec_ + -1],&fmcom_.x_[ipica_ + -1],&fmcom_.x_[ipicb_ + -1],
  &fmcom_.x_[iacon_ + -1],&fmcom_.x_[ibcon_ + -1],&fmcom_.x_[igmul_ + -1],&nsym_,
  &fmcom_.x_[iwrk_ + -1],&fmcom_.x_[ibo_ + -1],&jstsym_);
}
return ;
}
