I do as far as is possible all of my development under my stdlib's debug mode with -fsanitize=address and -fsanitize=undefined. If it's slow like this on my 2018 workstation, it'll be slow in release mode on my users's 2011 dual core laptops and on raspberry pis. but if you need a bit more speed you can still build with -O2 -D_GLIBCXX_DEBUG=1 -D_GLIBCXX_DEBUG_PEDANTIC=1 # for libstdc++ -O2 -D_LIBCPP_DEBUG=1 # for libc++ /O2 /D_ITERATOR_DEBUG_LEVEL=1 # for msvc this way you get compiler optimizations but the assertions are still there
