well...

(gdb) call debug_tree (t)
 <ssa_name 0x7ffff75338c0 nothrow var <var_decl 0x7ffff752faa0
prephitmp.162>def_stmt 

    version 447 in-free-list>

we release the SSA_NAME with remove_phi_node (&psi, true); before then
examining its uses ...

We forget to do so for the other stmts we remove.

An easy way out is to fix the tuplification.
