gdbm gdbm_open bug

[Jens Laas]

gdbm_open as GDBM_WRITER will create the db if not existing.
This should only happen in GDBM_WRCREAT.

( I am using Linux 2.4 and glibc 2.2.5 and gdbm-1.8.0 )

file gdbmopen.c

  /* Open the file. */
  need_trunc = FALSE;
  switch (flags & GDBM_OPENMASK)
    {

does not have a special case for GDBM_WRITER.
The default case is used which does:
      default:
        dbf->desc = open (dbf->name, O_RDWR|O_CREAT, mode);
                                           ^^^^^^^^
Cheers,
