Strings are different than numbers in that they don't occupy a fixed
amount of space, so some memory management is needed for them.

Thanks Martin,
Your PROTECT did the job :)

I'll start with this easy part. Unfortunately valgrind
didn't detect any wrong access to memory.
Now, the difficult part.
The most reduced code

Try running it under valgrind as well. E.g.,
% R --debugger=valgrind

Serguei,
First, I think we mentioned to you after your first post on rex2arma that all
serious Rcpp development is generally done in packages. You should probably
embrace that mode too. Many of us prefer it.
Second, 'expm' does not need to be reimplemented. See my RcppKalman package
(on GitHub
Hi everybody,
I am facing a volatile bug which appears and disappears in
identical calls on identical data.
My RcppArmadilla code is expm_cpp() (it is obtained by rex2arma tool
which I have presented before, cf. attached file). It is compared and
benchmarked vs its R counterpart expm.higham() (a
