The manual said

'It requires code to have been compiled and linked with -fsanitize=address'

I don't see that you linked with it ...

I have (in ~/.R/Makevars)

CC="gcc -std=gnu99 -fsanitize=address -fno-omit-frame-pointer"

and similar for F77, CXX ....

I guess PKG_LIBS=-fsanitize=address might work.
