The problem isn't with the -demo binary, but with the hacks that the
binary loads. On my -CURRENT system, libGL is linked to libpthread, and
so are my GL-based hacks:

I bet if you rebuilt xscreensaver without GL support, it would work
fine. I think adding PTHREAD_LIBS to the build may be the obly way to
fix this for libpthread users. =20
Of course, as a test, you might try libmapping libthread to libc_r, and
see if you can reproduce this, Alexander. I can try the same thing. I
know I can.
