           Summary: ld use huge memory and very long time when link
                    wxWidgets into single library
           Product: binutils
           Version: 2.22 (HEAD)
            Status: NEW
          Severity: critical
          Priority: P2
         Component: binutils
        AssignedTo: address@hidden
        ReportedBy: address@hidden


When I compile wxWidgets 2.8.12 into single library, ld use huge memory, I have
to use 64bit Linux to do cross compile:

CFLAGS='-pipe' CXXFLAGS='-pipe' LDFLAGS='-pipe -s -static' \
${HOME}/vcs/svn/wxWidgets/branches/WX_2_8_BRANCH/configure --prefix=/tmp/w32 \
  --host=i686-w64-mingw32 --with-odbc --with-opengl --enable-shared \
  --enable-unicode --enable-mediactrl --enable-official_build \
  --disable-compat26 --enable-abi-incompatible-features --enable-monolithic

When make finished, 454 object files generate one 12M file wxmsw28u_gcc.dll.

During the building, after ld running 25 minutes, the VM physical memory (3GB)
was exhausted, the host have 4 Xeon 3.20GHz CPU, and the other VMs were idle.

Maybe there have memory leaks in ld ?
