           Summary: bfd_getb32 in libbfd.c:609, crash in ranlib and nm
           Product: binutils
           Version: 2.21
            Status: NEW
          Severity: normal
          Priority: P2
         Component: binutils
        AssignedTo: address@hidden
        ReportedBy: address@hidden


I compiled binutils with

export lv_cv_sys_lib_search_path_spec="/lib64 /usr/lib64"
export lv_cv_sys_lib_dlsearch_path_spec="/lib64 /usr/lib64"
export LDFLAGS="-L/usr/lib64 -L/lib64"

./configure --enable-gold=yes --enable-ld=yes --disable-lto --enable-objc-gc
--enable-plugins --enable-64-bit-bfd --enable-targets=all
--enable-leading-mingw64-underscores --enable-elf-stt-common --with-zlib
--enable-install-libbfd --enable-threads

on x86_64 machine.  Now I want to compile gcc451 with 
../gcc-4.5.2/configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
--enable-threads=posix --enable-languages=all --enable-targets=all
--with-system-zlib

when it comes to building libgcj.a ranlib crashes.  The created core file
contains:

Loaded symbols for /lib64/ld-linux-x86-64.so.2
Core was generated by `ranlib .libs/libgcj.a'.
Program terminated with signal 11, Segmentation fault.

Bow, if I take libgcj.a from a previous compiled gcc451 and do
  nm libgcj.a
it crashes again and the core file says:

#0  bfd_getb32 (p=0x7f2f738d207e) at libbfd.c:609
609       v = (unsigned long) addr[0] << 24;
(gdb) bt

#4  0x0000000000403ea0 in display_file (filename=0x7fffc93a01e1 "libgcj.a")

#5  0x0000000000404b4b in main (argc=2, argv=0x7fffc939eea8) at nm.c:1671

so it comes again to libbfd.c:609.

Any ideas what could be wrong?
