#0 0x55cde700951d in operator new(unsigned long) (/build/built/linux/debug_asan/tests/SlowTests+0x197d51d) (BuildId: 5481b2fd59f45706447f0ea44f5af0db0c3788b7)

The code in question is: listeners()->SetDefaultResultPrinter(new PrettyUnitTestResultPrinter);

The PrettyUnitTestResultPrinter object leaks.

A simple fix is: static PrettyUnitTestResultPrinter pp; listeners()->SetDefaultResultPrinter(&pp);
