Reduced testcase, but a different ICE than the original one.

void Env_FetchObj0AttrOffset (unsigned int NumFields,  int *Status)
{
  int Found = 0;
  if (NumFields)      
    while ((*Status == 0) && NumFields-- > 0 && Found == 0)       
      Found = 1;
}

Reduced testcase for the original ICE:

void Env_FetchObj0AttrOffset (unsigned int NumFields, int AttrNum, 
                              int *Status, int *Vfields)
{
  int Found = 0;
  if (NumFields)  
    while ((*Status == 0) && NumFields-- > 0 && Found == 0)
      if (*Vfields == AttrNum)
        Found = 1;
}
