The problem is valgrind crashes imediately.
I am using Ubuntu 10.04 LST (actually Biolinux) on a 64bit Dell
Precision laptop with 4 core-i5 Intel processors. I have R-2-15-0
installed from source and configured using
./configure --enable-memory-profiling
--with-valgrind-instrumentation=2 --prefix=/usr/local/lib64/R-2.15.0-vg2
in /usr/local/bin there's a dynamic link
R-2.15.0-vg2 -> /usr/local/lib64/R-2.15.0-vg2/bin/R
I can run R in bash using
$ R-2.15.0-vg2
Valgrind was installed from the Ubuntu repositories using apt-get.
Simply removing this version and installing from source got things working.
Yes, I was about to comment that your valgrind is far too old for an
x86_64 system. Even 3.7.x gave spurious reports.
all the best

But ...
$ R-2.15.0-vg2 -d valgrind --vanilla
R-2.15.0-vg2 -d valgrind --vanilla

Note: see also the FAQ in the source distribution.
It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after
identifying problems in your program, there's a good chance
that fixing those problems will prevent Valgrind aborting or
crashing, especially if it happened in m_mallocfree.c.
If that doesn't help, please report this bug to: www.valgrind.org
In the bug report, send all the above text, the valgrind
version, and what OS and version you are using. Thanks.
I've used valgrind in the past on other computer without problem, but
I have no idea what's failling here (the FAQ didn't help). Does anyone
have any idea?
many thanks
David
p.s. I also have 2.15.1 installed in a near-identical manner as 2.15.0
with just the difference --with-valgrind-instrumentation=1, the result
is the same though.
