It will sometimes work.  It depends on which implementation of _Block_copy and 
friends the runtime linker decides to pick.  If it picks the one in libobjc2, 
everything is fine.  Otherwise, it is broken.

I thought that we’d modified libBlocksRuntime on FreeBSD to use weak symbols 
for various things, but it looks as if we didn’t and are just lucky with the 
link order...
