G'Day, ladies and gents;
I've got a program that I am trying to play around with. Once I've
added dlopen() using --export-dynamic, every time I try to run the
program, I get a segmentation fault. It always occurs on the same line
of code :
modules = new_module_pointer;
I can comment that line out, and suddenly the thing runs without a
hitch. However, I kinda need that line. When I run gdb on the core
dump, I get :

Does anyone have any ideas?
