Thanks for reporting.
By the way, I was compiling for Windows and had only compile time 
errors.

Made available on dpaste:
http://dpaste.dzfl.pl/7b5c36f8

On dpaste, the struct with an int didn't compile. (Same error 
message)


It turns out that

Template!(2, Sint).statArr()[0].writeln();

compiles with
$ dmd test.d -m64
but not with
$ dmd test.d

types only tested with dmd 2.062.


I can only replicate one of these bugs in dmd git master x64, 
the cfloat one. It segfaults during the initialisation of the 
array.


dmd calls _memset64 to do the initialisation. It seems to 
(partially) forget that we're in x64 and tries to pass the 
value to set to (float.nan) on the stack.


The result: A complete mess. Not enough arguments, in the wrong 
places.


_memset64 gets the right destination pointer but gets the 
length of the array (2) as the value to write and then tries to 
initialise RDX number of values. But RDX was never set. 
Segfault.


Sorry should specify this was on linux x64
