No, sorry. Under Windows DMD v2.069.2 it works perfectly in 
both cases.

Which compiler do you use?

- DMD64 D Compiler v2.069.2 on Linux.
- LDC 0.16.1 (DMD v2.067.1, LLVM 3.7.0)

I ran it now under Linux/Ubuntu DMD64 D Compiler v2.069.2

But both still worked..

Are there some characters in your input data which are invalid 
and not displayed in the forum?
(multiple empty lines after the actual csv data for example)

togrue

Indeed there's an empty line at the end of the csv.

Interestingly enough if I try with DMD64 D Compiler v2.069, the 
Fail version runs fine but the normal version returns:
std.csv.CSVException@/usr/include/dlang/dmd/std/csv.d(1246): 
Row 3's length 1 does not match previous length of 2.
I still do not understand half of the syntax(still learning) but 
my guess is that it is a bug in the csv reader:
In 
https://github.com/D-Programming-Language/phobos/blob/67c95e6de21d5d627e3c57128b4d6e332c82f785/std/csv.d line 1020 calls popfront on the input without checking that it input is empty.
But this only happen in special case if the last line is \r\n if 
i understand it correctly.
I might be totally wrong because it does not match your 
stackstrace and i did not yet understand everything about this.
