Hi, Thomas, Tomas,
Doesn't this issue demonstrate the warning and advice given in the last paragraph of section 6.6
of the "Writing R Extensions" manual:
<ref>
Passing character strings from C to Fortran or vice versa is not portable (and to Fortran 90 or later is even less so). We have found that it helps to ensure that a C string to be passed is followed by several nuls (and not just the one needed as a C terminator). But for maximal portability character strings in Fortran should be avoided.
</ref>
Avoid.
