Any help on this problem would be appreciated :

I'm having difficulties using GNU C++ with X11R6 under Linux.  My setup
is as follows : a Pentium PC running Linux (1.3.29), XFree86 (3.1.2) and
GNU GCC (2.7.0).  Everything is built to use ELF shared libraries.

The following short program works perfectly when compiled under GCC as
a C program, but when I use G++ to compile it as a C++ program (I use
C++ with X11 a lot, so this is necessary, it gives a seg. violation
somewhere in the XOpenDisplay and coredumps.

#include <stdio.h>
#include <X11/Xlib.h>
}

int main()
{
        printf("Calling XOpenDisplay\n");
        fflush(stdout);
        if (XOpenDisplay(NULL) == NULL) {
                printf("XOpenDisplay failed\n");
        } else {
                printf("XOpenDisplay succeeded\n");
        }
        return 0;
}

Interestingly, this only happens when DISPLAY is set to certain
addresses - as the following sample runs demonstrate.  It *looks* like
it works when it uses Unix-domain connections and fails when it uses
TCP/IP-domain connections...

$ g++ -o test test.cc -L/usr/X11R6/lib -lX11
$ DISPLAY=picasso.cs.tcd.ie:0.0 ./test
Calling XOpenDisplay
zsh: 1160 segmentation fault  DISPLAY=picasso.cs.tcd.ie:0.0 ./test
$ DISPLAY=:0.0 ./test
Calling XOpenDisplay
XOpenDisplay succeeded
$ DISPLAY=unix:0.0 ./test
Calling XOpenDisplay
XOpenDisplay succeeded
$ DISPLAY=picasso:0.0 ./test
Calling XOpenDisplay
zsh: 1163 segmentation fault  DISPLAY=picasso:0.0 ./test
$ DISPLAY=picasso/unix:0.0 ./test
Calling XOpenDisplay
XOpenDisplay succeeded

Any ideas?  This is really bugging me and I have no idea what is causing
it...  before I go re-compiling the X libraries with debugging on; I'd
like to see if anyone else has encountered this problem.

                 Colm.
