           Summary: gcc -flto hangs and allocates all memory
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c

        ReportedBy: sdack@gmx.de


Hello,

I have tried to compile gdb-7.2 with gcc 4.6.0 using -flto. In the final link
of gdb does the compiler get stuck and only seems to allocate more and more
memory (>8GB) without ever returning.

I have seen it doing the same when compiling ffmpeg-0.6.2 with gcc 4.6.0 using
-flto.

Without -flto do both packages compile successfully.
