This has nothing to do with dl, it's just bad fortune that the crash
happens only in this situation.

Clone expects the *end* of the stack as the argument. I.e.,
clone (foo, stk + 1024 * 1024, ...)
But you shouldn't use clone() in the first place. The libc will not
be thread safe unless you link against libpthread (or use define the
needed magic in your programs as well).
