           Summary: [C++0x] Segment Fault When Compiling
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: critical
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: neuront@bitfoc.us


Created attachment 23729
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=23729
source file and temp file.

Source file that leads to crash is in attachment, named as function.cpp, along
with temp files function. ii and function.s

The following is what I did to compile the source and the output by the
compiler.

$ gcc -std=c++0x function.cpp
In file included from
/usr/local/lib/gcc/i686-pc-cygwin/4.7.0/../../../../include/c++/4.7.0/memory:85:0,
