Dear all
I have bumped into the dreaded 'segfault' error type when running some C++ code
using .Call().
I have already undertaken several attempts to debug the C++ code with gdb(),
but until now I have been unable to pinpoint the origin of the problem. There

I have found out that the max in the summary of an integer vector is not always
equal to the actual maximum of that vector. For example:

I am estimating a model with instrumental variables using ivreg() (from the

continuous variables, things work fine.
However, I have some regressors, such as "income", for which I only have

I want to call R repeatedly in batch mode from a bash script that is then

My calls to R depend on optional arguments.
When I introduce these arguments as literals, the calls work fine, for instance:

Dear all,
I use R version 2.15.1 on x86_64-pc-linux-gnu (64-bit).

\bin\i386 (I had copied an old batch file, and overlooked this).
The problem is solved now.
