Just back from my travel.
The sanitizer error message disappeared on trunk level 246252.

Traveling now, back home end of March.
Did you check the value of variable "len" maybe it's zero so it's not
really a bug.

I cannot reproduce this PR even with an instrumented compiler. How do you get
the error?

Still in trunk:

../../gcc7/gcc/fortran/data.c:191:32: runtime error: null pointer passed as
argument 2, which is declared to never be null

here:

memcpy ([start], rvalue->value.character.string, len * sizeof
(gfc_char_t));

Probably len==0 and preponing an if(len) should do the trick

Still in gfortran 5.3.0

/home/vitti/gcc-5.3.0/gcc/fortran/data.c:191:32: runtime error: null
pointer passed as argument 2, which is declared to never be null

data.c:191 "memcpy ([start], rvalue->value.character.string,
len * sizeof (gfc_char_t));"

Maybe len==0

Can you please check that it has not been fixed by r229153 for pr67939 (trunk
6.0) and r229555 (5.2.1)?
