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).

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?

Many thanks in advance

Erika
