[Octave-bug-tracker] [bug #47372] Memory leaks and segmentation faults in Octave

[John W. Eaton]

Follow-up Comment #18, bug #47372 (project octave):

When I just run make test (instead of running tests in batches) I see the
following result:


  libinterp/dldfcn/fftw.cc-tst ................................ PASS     13/13
 
  libinterp/dldfcn/qr.cc-tst ..................................ASAN:SIGSEGV
