Perf test 14 failing

all the test cases given in the files have been passed but only perf test 14 is failing.
perf-input.txt file has also passed tests.
when I ran this command diff pref-output-1.txt myout.txt
the only difference was

HEAD is now at 978674b [crio]: lib first commit

tried prep-14.txt got this error: terminate called after throwing an instance of ‘std::bad_alloc’
what(): std::bad_alloc
Aborted (core dumped)
