--- Comment #10 from Paul Floyd <pjfl...@wanadoo.fr> ---
Loading of shared libraries is done with mmap. So whenever Valgrind sees an
mmap it reads the file to see if is an ELF binary and to determine if it needs
to read the DWARF debuginfo. The assert that you are seeing happens during this
check (vgModuleLocal_check_elf_and_get_rw_loads). It looks like the mmap
syscall is succeeding (which would also mean that the open succeeded).

The failure is here

      SysRes sr = VG_(pread)(img->source.fd, &ce->data[0], (Int)len, off);
      vg_assert(!sr_isError(sr))

I'll see if I can reproduce the problem on Linux.
