# HALT: llvm-xray: Found record {FuncId: "#4", ThreadId: "111", RecordType: "Fn Exit"} with no matching function entry
#KEEP-GOING-SUCCEEDS: Found record {FuncId: "#4", ThreadId: "111", RecordType: "Fn Exit"} with no matching function entry
#KEEP-GOING: Unique Stacks: 2
# Note the interesting case here that the stack { fn-1 } is a prefix of { fn-1, fn-2, fn-3 } but they
# are still counted as unique stacks.
