           Summary: [4.9 Regression]: comp-goto-1.c: ICE verify_flow_info
                    failed, error: EDGE_CROSSING missing across section
                    boundary
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: rtl-optimization

Relatively new regression, can be triggered with crosscompiler from
x86_64-pc-linux-gnu to alpha-linux-gnu:

../gcc-svn/trunk/configure --target=alpha-linux-gnu --enable-checking=yes

Running:

~/gcc-build-alpha/gcc/cc1 -O2 -freorder-blocks-and-partition -fprofile-use
-mexplicit-relocs -fpreprocessed comp-goto-1.i

results in:

comp-goto-1.c: In function ‘simulator_kernel’:
