This is a issue with dead code elimination, I filed a bug report about it.

Hint: the -O and --optimize option allows also a syntax for excluding
optimizations. This is very useful for finding what optimization may
cause a bug. For example, to enable all the optimization but dead code
elimination and inlining, you can use:

	-O=all,-deadce,-inline

In the same way, if you want to enable just one optimization, use:

	-O=-all,deadce

The .so binary is a shared library, you can't execute it directly.
mini will load it automatically whenever you try to execute the assembly
it was generated from.
