           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal

        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: markus at oberhumer.com

This is the result from a bugpoint session:

*** The following functions are being miscompiled:  ucl_alloc main
l1_ucl_alloc_entry_2E_UnifiedReturnBlock_crit_edge l2_ucl_alloc_shortcirc_next
l3_ucl_alloc_endif_2E_i l1_ucl_alloc_UnifiedReturnBlock_2E_i
l1_ucl_alloc_ucl_malloc_internal_2E_exit_2E_ce l1_ucl_alloc_UnifiedReturnBlock
Outputting reduced bytecode files which expose the problem:
  Non-optimized portion: Emitted bytecode to 'bugpoint-tonotoptimize.bc'
  Portion that is input to optimizer: Emitted bytecode to 'bugpoint-tooptimize.bc'

*** You can reproduce the problem with: opt bugpoint-tooptimize.bc
