Dear R developers,
I've got an information from Prof. Ripley regarding a bug found
with AdressSanitizer in one of our packages. It is now fixed, thank
you for this information.
Now, I would like to run AddressSanitizer myself before submitting
the patched package to CRAN.
Is there a recommendation of a suitable Linux distribution with gcc
4.8, ideally an ISO image or (even better) a virtual appliance for
VMware or VirtalBox? My Debian Wheezy machines have only 4.7.2.
Thank you
Thomas Petzoldt
I am not sure about all the requisites above (regarding the virtual
appliances although I know that they are available) but Fedora 19
(Alpha) that will be released today has gcc 4.8.
Even although it has the Alpha moniker, and the corresponding stage,
it is relatively stable and thus suitable for your requirements.
Regards,
Thank you for the hint to use Fedora 19 Alpha. I have it now running,
together with R 3.0.0. and gcc 4.8.0 20120412 (Red Hat 4.8.0-2).
Compilation and installation of packages (without ASAN) workes out of
the box.
Then I've set:
export PKG_CFLAGS="-fsanitize=address -fno-omit-frame-pointer"
... and compilation runs and I see that gcc uses the flags, but package
installation still fails:
** testing if installed package can be loaded
Error in dyn.load(file, DLLpath = DLLpath, ...) :
unable to load shared object
'/home/user/packages/deSolve.Rcheck/deSolve/libs/deSolve.so':
/home/user/packages/deSolve.Rcheck/deSolve/libs/deSolve.so: undefined
symbol: __asan_report_load8
Error: loading failed
Execution halted
ERROR: loading failed
I see that the address sanitizer cannot work yet (__asan_report_load8)
and that I missed something important, but what?
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.
