rtld problem

[Robert Swindells <rjs%fdy2.co.uk@localhost>]

Is anyone else getting core dumps when running dynamically linked
programs ?

An example backtrace for ifconfig is:

#0  0x00007f7ff7c0b79f in memcpy () from /libexec/ld.elf_so
#1  0x00007f7ff7c04302 in _rtld_do_copy_relocation (dstobj=dstobj@entry=0x7f7ff7ef9000, rela=<optimized out>, rela=<optimized out>) at /u1/src/libexec/ld.elf_so/reloc.c:105
#2  0x00007f7ff7c04405 in _rtld_do_copy_relocations (dstobj=0x7f7ff7ef9000) at /u1/src/libexec/ld.elf_so/reloc.c:147
#3  0x00007f7ff7c03029 in _rtld (sp=<optimized out>, relocbase=<optimized out>) at /u1/src/libexec/ld.elf_so/rtld.c:733
#4  0x00007f7ff7c007a3 in .rtld_start () from /libexec/ld.elf_so
#5  0x0000000000000000 in ?? ()

This is with sources from today on amd64, including latest binutils.

It looks as if the mapbase and relocbase members of the Obj_Entry struct
are set to unmapped addresses.
