Network Runtime Linking shared Objects

I'm runtime linking (dlopen and dlsym) to a shared object (library) I've created and after a number of function calls into the library the program core dumps (Illegal operation). This only occurs during runtime linking. If I use the same library and dynamically link during compile time everything works perfectly.

I've tried different compilers and linking modes, but nothing seems to work. Lately I've been checking my code for bugs even though it's odd that everything works except during runtime linking.

Has anyone experienced anything like this and know what the problem/solution is.

Brief background info:
platform: SunSolaris
library compile options: -fPIC
library link options: -shared
executable compile options: -fPIC
executable link options: -ldl

That's it.

NAME
apr-1-config - Return metainformation about apr library SYNOPSIS
apr-1-config [OPTION] DESCRIPTION
The apr-1-config program is used to retrieve information about the apr library in the system. It is typically used to compile and link against the library. When linking with libtool, an application should do something like: APR_LIBS="`apr-1-config --link-libtool --libs`" or when linking directly: APR_LIBS="`apr-1-config --link-ld --libs`" An application should use the results of --cflags, --cppflags, --includes, and --ldflags in their build process. OPTIONS
Known values for OPTION are: --prefix[=DIR] change prefix to DIR --bindir print location where binaries are installed --includedir print location where headers are installed --cc print C compiler name --cpp print C preprocessor name and any required options --cflags print C compiler flags --cppflags print C preprocessor flags --includes print include information --ldflags print linker flags --libs print additional libraries to link against --srcdir print APR source directory --installbuilddir print APR build helper directory --link-ld print link switch(es) for linking to APR --link-libtool print the libtool inputs for linking to APR --shlib-path-var print the name of the shared library path env var --apr-la-file print the path to the .la file, if available --apr-so-ext print the extensions of shared objects on this platform --apr-lib-target print the libtool target information --apr-libtool print the path to APR's libtool --version print the APR's version as a dotted triple --help print the help AUTHOR
