I am having the problem described in this post:
https://stat.ethz.ch/pipermail/r-sig-mac/2011-November/008848.html
In summary, running Valgrind with R hangs.
As in the linked case above, if a file test.R contains the single command
print(seq(10))
Then running the command
R -d "valgrind --tool=memcheck --leak-check=full" --vanilla < test.R
Produces the following output and hangs

I have followed the advice previously posted by Simon, used the SVN build of
valgrind and recompiled R from source with --with-valgrind-instrumentation=2
I am running Mac OS X 10.6.8, valgrind-3.9.0.SVN, R version 2.15.1 and
Platform: x86_64-apple-darwin10.8.0/x86_64 (64-bit).
As was the case for the previous poster, a command such as
valgrind ls
works as expected.
I noted that Simon said he had no problem using valgrind from SVN on
both Lion and Snow Leopard. Does anyone have any suggestion of what
I might be doing differently, or what I could do to fix this
problem?
Not multiple post ... this is a second copy.
It does not work for me on Lion (I've never tried Snow Leopard). As
valgrind does not yet (even in the recent 3.8.0) really support
Mountain Lion and we will be upgraded shortly (and BTW, Snow Leopard
is now end-of-life for security patches), I've pretty much given up on
valgrind on OS X.
