Gentlepeople:

The situation is as follows:

We have a Sparc server running Solaris2.6, with Rational Apex as the ada
development system, and gcc as the c compiler.  The workstations are PCs
running the eXceed x- server.

 We downloaded and installed the Intermetrics X11Ada bindings to Ada95 on
the server.

They installed ok, but programs compiled and linked using them crash. The
crash is usually in an area where the program is trying to use data from the
display structure returned from XOpenDisplay.

1) we are using the correct hostname: server string in the display_name
parameter to XOpenDisplay.

2) Other X programs not using the bindings work just fine.

     There are two versions of the x-library (one in /usr/lib and the other
in /usr/openwin/lib). I've linked basicwin and curves (bindings test
programs) to both and  gotten the same result, therefore eliminating the
possibility that I've linked in the wrong library version.

     I've run two versions of both basicwin and curves (linked to the two
sets of libraries) from a Sun machine, eliminating Exceed as the cause of
the problem.

     I wrote a little C program which makes some of the library calls that
are crashing the Ada programs and then prints out the results, which look
fine.

     I think this pretty much eliminates any source of problems aside from
the compiler/linker and the bindings themselves, and I'm starting to suspect
Rational.

If anyone has experienced these problems before, any help would be
appreciated.

Thanks
