static void * oops[1] = { &oops - 1 };
is represented internally as "Add P(Address P[oops], Const Is<0xFFFFFFFC>)".
This eventually results in the generated assembly being
oops:
.long oops + 0xfffffffc
Which will fail to assemble if the resulting value doesn't fit into 32 bits (e.g. if there's other static data before this in the file).
(Of course, when using the amd64 backend, the resulting constants are longer, but the problem persists)
I've attached a somewhat minimal example that triggers the problem.
