[R-pkg-devel] debugging memory errors

[Henrik Bengtsson]

There's also R Hub by Gábor Csárdi:

  https://builder.r-hub.io/advanced

It provides a win-builder-like service where you can test your package
with different R setups, including 'Debian Linux, R-devel, GCC
ASAN/UBSAN'.  There's also an 'rhub' package that allows you to run
all this from the R prompt.

It's simply great.
