H�!

I work under SunOS 4.1.4 2 sun4m
with gcc 2.7.2.1

- I link a called lib.so File to two different other .so Files.
- These different other .so Files shall be loaded one after another
  by a main-prg. 
- In trying to load the second of the two different .so Files I get
  following error:

        ld.so: conflicting usage of dlopen'ed dependents

There is no problem on a sun3 under SunOs 4.1,
so it's obvious, that sun4 dynamicl loader has a problem.

No problem on

SunOS kussun1 4.1.1 2 sun3

but on 

SunOS kussun2 4.1.2 2 sun4c
error: ld.so: conflicting usage of dlopen'ed dependents


Does somebody know, if this problem is known?
Exists even a patch?

If not: 
1.) what can I do to work around?
2.) Is there a way to inform sun about the error?
    I couldn't find an entry on there homepage to to so.
   They don't offer free support. (My university don't get support)
3.) Is there a possiblity to initiate a patch or is there no support
     of  Solaris 1.1.2 since Solaris 2 exists?


To give you the possibilty to test if it works on your system there is
a small test -prg and makefile. Please let me know on what SunOS you
tested it and what happend.

Thank you very much for helping.

Greetings

                Frank.
