>From https://www.stats.ox.ac.uk/pub/bdr/memtests/gcc-ASAN/rTLS/00check.log, you can see errors of the form:
==3566104==ERROR: AddressSanitizer: stack-use-after-scope on address 0x7fffc2651f80 at pc 0x7f7ba5b635de bp 0x7fffc2651eb0 sp 0x7fffc2651ea0 < ... > The slides here explain what that means in more detail: https://llvm.org/devmtg/2016-11/Slides/Buka-StackUseAfterScope.pdf But, in short, it usually means you took a reference to a variable on the stack, and then tried to access memory via that reference after that variable went out-of-scope. Based on the associated code here: https://github.com/Antguz/rTLS/blob/449b5c98942a37d4d98d4d2d27ac04caf3cc2cb6/src/knn_rcpp.cpp#L20-L48 A guess is that the issue is related to your use of the non-copying arma::mat constructors + attempts to transpose them. Could you use .inplace_trans() instead? You can also try to verify locally using e.g. Docker; the rocker images here are immensely helpful: https://github.com/rocker-org/r-devel-san Best, Kevin On Fri, Apr 16, 2021 at 8:43 AM J.
