I'm ready to admit that I didn't read the code well enough, but it seems to me that the vector resized on line 752 resides in std::vector<WorkerMemory> worker_memory allocated on lines 411-415 in int fit_iforest(...) and then disposed of by the end of the function. I don't see workspace.ix_arr being saved anywhere model_outputs(_ext). I think that workspace.ix_arr shouldn't even exist by the time the lines following isolation.forest(...) are executed. Can you reproduce the warning on your own computer? It might be helpful to run R -d 'valgrind --vgdb-error=1 --vgdb-stop-at=startup', follow Valgrind's instructions to attach the debugger to it, type "continue" into gdb, then trigger the warning in R and use gdb to gather more information when Valgrind stops the process around the memory access it considers uninitialised. -- Best regards, Ivan ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
