Checking packages with address sanitizer
...ls) because
there were issues reported by address sanitizer.
Therefore the problem of installing and running instrumented (R +) package
code arises.
Regrettably up to now, I found no way to use the address sanitizer, neither
for a small C-example nor for a new compiled version of R.
I get missing `__asan_report_store4' or `__asan_report_load4' messages.
I'm working on Ubuntu 13.10 and tried gcc (4.8.1) and clang (3.2-7ubuntu1,
based on LLVM 3.2).
Does anyone have experiance with address sanitizer (especially with a self
compiled R-version which is not in the standard location on the system)?
Thank...

[LLVMdev] [cfe-dev] Address sanitizer regression test failures for PPC64 targets
Note that I've set the SA_NODEFER flag for the SEGV handler in the
ASan runtime only a couple of days ago.
Not sure that could've affected this test though; without that flag
the second SEGV would've simply crashed the program. But you can try
removing the flag from
compiler-rt/trunk/lib/sanitizer_common/sanitizer_posix_libcdep.cc and
see if that makes any difference.
HTH,
Alex

Indeed, removing that flag works fine, the only question is why this is
added in tools/llvm-shlib/Makefile in the first place then and what to do
about it:
ifeq ($(HOST_OS), $(filter $(HOST_OS), Linux GNU GNU/kFreeBSD))
# Don't allow unresolved symbols.
LLVMLibsOptions += -Wl,--no-undefined
endif
