3.3.8 fails on SW8.1

[Bob Toxen]

I utterly love DDD and think that it's the best use of GUI technology
that I've ever seen (and I don't usually like GUI programs).  I even
mentioned it in my book, Real World Linux Security.

However, DDD 3.3.8 does not compile on my stock Slackware 8.1 system.

The configure script can determine that it's a Slackware system by the
presence of the /etc/slackware-version file.  On SW8.1 its contents are:

     Slackware 8.1

There is a conflict between the SW file:

  /usr/lib/gcc-lib/i386-slackware-linux/2.95.3/../../../../include/g++-3/string

when compiling the file ddd.C:

It seems to have the same problem on RH7.3 (my other standard platform):

======================================================================

3.3.7 fails on each platform similarly.  Very disappointing.

======================================================================

3.3.1 builds and runs successfully on RH7.3.

However, 3.3.1 (and 3.1.3) has a bug in that they do not check the
return code from ptrace() for errors.  I have created a no_ptrace()
kernel loadable module to block the invocation of ptrace() on Production
systems, including my main development system, due to the recent security
bugs found in ptrace().  When I tried to use DDD to debug a program I
forgot about the no_ptrace().

DDD allowed me to set breakpoints without complaint.  However, when I ran
the program under test none of the breakpoints interrupted execution.
In other words, it did not detect that ptrace() was return an error
and not alerting the user.  Perhaps this is a bug in gdb instead.
