            Bug ID: 58864
           Summary: [4.8/4.9 regression] ICE in connect_traces, at
                    dwarf2cfi.c:NNNN
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ppluzhnikov at google dot com

Google ref: b/11306585

Attached test case causes ICE with current trunk (g++ (GCC) 4.9.0 20131016
(experimental))

As far as I can tell, 4.7 is fine, but 4.8 and above is broken.

g++ -Os -m32 -c t.cc

t.cc: In member function âvoid L::compute()â:
t.cc:69:1: internal compiler error: in connect_traces, at dwarf2cfi.c:2686
