[R-pkg-devel] how to change from -fsanitize=undefined to -fsanitize=address

[Youyi Fong]

Thanks. I was wondering how to do that within the context of docker
containers. In the tutorial
http://dirk.eddelbuettel.com/code/sanitizers.html, one calls the prebuilt
Rdevel:

# Rdevel CMD INSTALL sanitizers_0.1.0.tar.gz

and get

* installing to library '/usr/local/lib/R/site-library'
* installing *source* package 'sanitizers' ...
** package 'sanitizers' successfully unpacked and MD5 sums checked
** libs
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
g++-4.9 -fsanitize=address -I/usr/local/lib/R/include -DNDEBUG
-I/usr/local/include    -fpic  -pipe -Wall -pedantic -O3  -c
stack_address.cpp -o stack_address.o
g++-4.9 -fsanitize=address -shared -L/usr/local/lib/R/lib
-L/usr/local/lib -o sanitizers.so heap_address.o stack_address.o
-L/usr/local/lib/R/lib -lR
installing to /usr/local/lib/R/site-library/sanitizers/libs
** R
** inst


But the same thing does not happen to me. I got -fsanitize=undefined
instead. I did try modifying Makevars, but it did not seem to have an
effect.
