e.g. in x86_64.ubuntu20.dnsmasq.clang.O0.nopie.nostrip/x86_64.ubuntu20.dnsmasq.clang.O0.nopie.nostrip.elf:

The function is defined as:

define i64 @cache_get_name({ <52 x i8>, i32, { }* }* %arg0) {

Yet, in the final block we infer a pointer type for the return value:

block_0_403d83:
  ; r22
  %t29 = phi { }* [ %t11, %block_0_403d3d ], [ %t25, %block_0_403d61 ], [ %t28, %block_0_403d72 ]
  ret { }* %t29

These are incompatible.
