Follow-up Comment #6, bug #53507 (project octave):

I'm no expert on the Sparse type, but it looks to me like symbfact isn't
populating the data array until the very end. Until then it's completely
uninitialized. It might be the transpose on line 338 that is copying
uninitialized bool values from one data array to another
(https://hg.savannah.gnu.org/hgweb/octave/file/135cc24efe4c/libinterp/dldfcn/symbfact.cc#l336)
before the data is actually filled in on line 342.
