Hello, I would like to reproduce this error locally: https://www.stats.ox.ac.uk/pub/bdr/memtests/clang-ASAN/chngpt/00check.log I followed the tutorial at http://dirk.eddelbuettel.com/code/sanitizers.html, but what happened to me was not g++-4.9 -fsanitize=address -I/usr/local/lib/R/include -DNDEBUG -I/usr/local/include -fpic -pipe -Wall -pedantic -O3 -c heap_address.cpp -o heap_address.o but g++-4.9 -fsanitize=undefined -I/usr/local/lib/R/include -DNDEBUG -I/usr/local/include -fpic -pipe -Wall -pedantic -O3 -c heap_address.cpp -o heap_address.o And when I test my package, chngpt, I was not able to reproduce the error on CRAN. I am guessing that if change the compiler option from -fsanitize=undefined to -fsanitize=address, I might be able to reproduce the error. My question is how. Thanks!
