Program which crashes when run.

While trying to statically include a library for a game, I compiled with both
'-shared' and '-static'. I ran the program and it crashed with "Segmentation
fault".
I reduced the program down to the minimum required to make it crash. When I
compiled the test with 'gcc -o segment_test -shared -static main.cpp' and ran
the program ('./segment_test'), the program still crashed with the same error
as the original.

"-shared -static" does not make sense really.  Are you trying to compile a
libary that contains all other libraries compiled staticly?  If so then
"-shared -static" makes sense.  It does not produce an application but rather a
shared library.

I was trying to make it prefer static libraries to shared libraries.

-shared is forcing a creation of a shared library while -static is forcing the
libraries to be staticaly linked.  So this only makes sense if you have forcing
static libc (etc.) for a shared library.  If you force a static library use
-Wl,-Bstatic -lxyz -Wl,-Bdynamic .
