Looks like selection is failing to set a register class:
LLVM ERROR: VReg has no regclass after selection (in function: f)
Converting the bitcode to LLVM IR we get:
source_filename = "M"
define void @f() {
BB:
br label %BB1
BB1: ; preds = %BB
%G13 = getelementptr i16*, i16** undef, i1 false
%A6 = alloca i1
%A2 = alloca i1*
%C1 = icmp ult i32 2147483647, 0
store i1* %A6, i1** %A2
store i1 %C1, i1* %A6
store i16** %G13, i16*** undef
ret void
}
