Hello Jonhatan and Dirk,
It seems that the whole issue that I encountered was contained in this
"off by 1" in the loop. I feel a bit stupid for that :).
I can now compute the operation 10^8 times (embedded in another
function) without any problem so far, and without using R function gc().

Excellent point. And the "Writing R Extensions" manual has a few tips.
Reading the output of valgrind takes a little getting used to thou

I was just giving some tips in case you needed to look at the output from
Valgrind. When using the prefix, Valgrinds messages didn't lead me right to
Hello Jonathan,
Thanks a lot for your help.
I didn't know valgrind, but i'll definitely go into it. Thanks very
much for your help.
So, you think I should go to postfix increments instead of prefix?
I'm a beginner in C++, so I'm not comfortable on which of them to chose.
You seem to be righ
Pierre,
Have you used a tool like Valgrind? There is a bit of a learning curve, but
it is exceedingly useful.
A few comments:
1) For cases likes this gctortute(TRUE) in your R script helps those “for
enough iterations in a loop…” bugs to present quickly. With gctorture(TRUE)

Hello Dirk,
I will do what I can to reduce the code and have to same error occuring.
Of course i don't expect you to read all of it :) I was just wondering
if that kind of memory problem occured before, and if has some
"typical/generic" solutions.
I will try to have a shortest code to exhibi

Hello Dirk, and everyone,
I sadly was too optimistic thinking that a gc() would solve the problem.
The main_function_C I wrote was putted in a more general function

Hello,
I have found out that the problem was in the R loop, the garbage
collection of R wasn't perform efficiently. Indeed, when I force the
garbage collection to be done, using R function gc(), the Rsession
won't crash, although the execution of the loop will be slower.
This leads me to an
