I'm currently checking my code for bugs because that's always usually the problem. However, know that I'm not doing a static link at all. The compile link and runtime link are both dynamic to the same -fPIC compiled library. And the only difference between the two types of links that I know of is that the library is loaded with the executable by default on a compile link and at my discretion on a runtime link. Also the code runs totally fine on Win32 no matter what kind of linking I do. It also runs fine with a compile link (dynamic) on the Dec Alpha unix platform. Granted the library I've written is extremely complex, so the chance of bugs are great, that just seems odd to me.

The code is running fine in all situations except this one so I'm trying to be sure I am not missing something when it come to runtime linking on Unix, like a buggy operating system library loader, a linking step, or something.

Thanks again.

libdl

libdl(3LIB)							Interface Libraries						       libdl(3LIB)

NAME

       libdl - dynamic linking library

SYNOPSIS

       cc [ flag... ] file... -ldl [ library... ]

DESCRIPTION

       Historically, functions in libdl provided for dynamic linking support. This functionality now resides in libc(3LIB).

       This  library  is  maintained  to provide backward compatibility for both runtime and compilation environments. The shared object is imple-
       mented as a filter on the runtime linker. See ld.so.1(1). New application development need not specify -ldl.

INTERFACES

       The shared object libdl.so.1 provides the following public interfaces. See intro(3) for additional information on shared object interfaces.

       dladdr			     dladdr1
       dlclose			     dldump
       dlerror			     dlinfo
       dlmopen			     dlopen
       dlsym

FILES

       /lib/libdl.so.1		       shared object

       /lib/64/libdl.so.1	       64-bit shared object

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
