When you open a .dll (or .so) on Linux the _init()
entry point is called. When you close a .so the _fini()
routine is called, if it's defined. Almost all of the .so's
on your list export _init() and _fini() symbols.

Your program goes blindly through a list of 500 shared libraries,
opening and closing them, causing _init() and _fini()
routines to be invoked. You don't know what all those libraries
do, or how they are supposed to be used. It doesn't
surprise me that in one or two cases some instability might occur,
just by opening and closing, leading to an eventual
segmentation violation.
