And here is a call stack from module destructor which in this case workd as
UnloadDetector:
#1 0x00007ffff68f4921 in __GI_abort () at abort.c:79
#2 0x00007ffff0a5ff89 in PluginModule::~PluginModule (this=0x7ffff0f971b0 <module>,

#6 0x00005555555760fa in _start ()
Obviously library's onexit handler that destruct global variables is called before
application's one in glibc 2.27.
