Hi,

I changed the flags of dlopen in dynlib.c:

dynlib_handle_ptr
dynlib_open (const char *path)
{
  // return dlopen (path, RTLD_LAZY);



  return dlopen (path, RTLD_LAZY|RTLD_GLOBAL);
}

then my dynamic module can load other .so in emacs-27.

but it make gccemacs-28 crash:

$ /usr/src/emacs/src/emacs -nw -q
