Fortran strings can contain '\0', so assuming that '\0' is the string
termination character may lead to problems.  Does code, which is not
there for debugging only, depend on NUL-termination of strings?


As far as I have been able to see, '\0' is not assumed to be the
string termination character. What is assumed is that
value.character.string points to a series of value.character.length+1
bytes, the last one being '\0'.

So, AFAICT, there should be no problem with strings containing '\0'.
