           Summary: [3.3 regression] [IA64] Compiler generates infinite loop
           Product: gcc
           Version: 3.3.2
            Status: UNCONFIRMED
          Keywords: wrong-code
          Severity: normal
          Priority: P2
         Component: optimization
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: schwab at suse dot de
                CC: gcc-bugs at gcc dot gnu dot org
GCC target triplet: ia64-suse-linux

The compiler generates an infinite loop from this part of the testcase: 
 
      for (size_t i = 0; i < siblings.size(); ++i) { 
        std::vector <Node> new_siblings; 
 
        if (! fetch(siblings[i], new_siblings)) { 
          array[begin + siblings[i].code].base = 
            val ? (ArrayType)(-val[siblings[i].left]-1) : (ArrayType)(-siblings
[i].left-1); 
 
.L925: 
	.mfb 
	ld8 r14 = [r15]	//  <variable>.val 
	nop.f 0 
	nop.b 0 
	;; 
	.mib 
	cmp.eq p6, p7 = 0, r14 
	nop.i 0 
	(p7) br.cond.dptk .L925
