Tobi,

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?

I will in the next 24 hours check if this fixes the remaining iso_varying_string testcases, which die a death on zero length strings. I suspect that it will help ;-)

Paul
