             Bug #: 50432
           Summary: lto1.exe: internal compiler error: in
                    cgraph_mark_functions_to_output, at cgraphunit.c:1173
                    when build Qt4.7.4 rcc
    Classification: Unclassified
           Product: gcc
           Version: 4.6.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: lto
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: xunxun1982@gmail.com

            Target: *-*-mingw32
             Build: *-*-mingw32


If I use gcc4.6.1 to build Qt4.7.4 with "-flto -fuse-linker-plugin", it will
result in an internal compiler error when building rcc:

g++ -Wl,-s -flto -fuse-linker-plugin -Wl,-subsystem,console -o
../../../bin/rcc.exe tmp/obj/release_shared/rcc.o 
tmp/obj/release_shared/main.o 
-L'e:/new/GUI/Qt/qt-everywhere-opensource-src-4.7.4/src/tools/bootstrap/release'
-lbootstrap -luser32

It's strange that after I update to gcc4.6.2.20110916, the issue is gone.

I review my earlier build process, and I found that the issue only came out if
you built your gcc with "-flto".

So bug can be closed AFAIU?
