What do you mean it doesn’t work as expected ? What did you expect and what happened instead ?

I am not sure about him but in my case close-foreign-library crashes with "Inconsistency detected by ld.so: dl-close.c: 765: _dl_close: Assertion `map->l_init_called' failed!". No backtrace, nothing.

Archlinux sbcl-git: SBCL 1.1.5.5-203e2ac
I got the same crash with Archlinux standard sbcl package.

What do you mean, Arch Linux? The above snippet loads user32.dll, which is a Windows library.

10 years later, Serhiy Yakovyn's example seems to work fine on SBCL 2.0.2 / Windows. 🎉
