12# We simulate the case when, for whatever reason, we see that a thread's stack
13# is empty when we see an EXIT record. This can happen for example when an
14# instrumented function does a 'fork()', where the child process will not see
15# the entry record but see the exit record. This is completely valid data,
16# which should be handled with grace (i.e. we treat it as an error, but since
17# the llvm-xray account tool has an option to keep going, gives the user a
18# chance to retry).
