I am just experimenting with a plugin loader and I found

The solution is to add RTLD_GLOBAL to the dlopen mode,
but I am not sure if this would cause other problems.
So your plugin loader provides symbols that subsequently loaded plugins
use? What are those symbols and what are they used for? Maybe there's a
more appropriate way to provide those symbols to the plugins.
I am not actually providing symbols directly, I am linking
to python, but not all of the symbols are being exported to
be used by dynamically loaded python modules.
An example is the python open gl module. As soon as that loads
it tries to read some python symbols which I do not use.
I tried different ld flags but none of those seem to work. An
alternative is to dlopen libpython from within the loader plugin
or preload libpython.
My problem is similar to this one
