Roll is specifically for cases where you want one of the fields to increase or decrease without affecting the others (e.g. if you had a spin control in your GUI with a DateTime backing it and didn't want any units other than the currently altered unit to change when its value wrapped around). In most cases, you're simply going to want to add a Duration to it - which dt + days(n) or dt + n.days will do. - Jonathan M Davis

That is lavish. You should use a bool inside the struct Cell. If it's false, the cell is not displayed and is out of the game. My suggestion: don't use the D GC, it's crap. Try to circumvent the GC wherever possible. Therefore you should use the -vgc compiler flag and the @nogc attribute.
Re: Conway's game of life
1. I prefer alias CellList = Cell[]; over alias Cell[] CellList; 2. Do you really need to create a complete new CellList for every single removal? If so, you'd know the size of the new list in advance and can allocate it directly at the correct size. I get the impression that you think Cell[] is a linked list but it's an array slice.

RHS is probably short of "right hand side", ie. the argument on the right side of the operator in a binary operator expression. In `a < b` it would be b. I am trying to do something like this: if( DateTime.opCmp(dtindb, outoftime)); But it's seems that I wrong understand how to use this function... No. That would be `if (dtindb.opCmp(outoftime))`, but it's simpler to write `if (dtindb < outoftime)`

Does anyone have any ideas of what could have caused this?
What is the source code of your main function?
I ask because it looks like it did. frame 13 is C main. frames 12
- 8 are compiler generated.
Frame 7 is D main.
frame #7: 0x00010c06 vision_entry`_Dmain + 86 at
stdio.d:2727
Frame 6 is std.stdio.writefln(...)
Frame 5 is the acquisition of the locking text writer
frame 4 is the constructor of the locking text writer. THIS IS
WHERE THE EXCEPTION IS THROWN.
as is evident by frame 3.
vision_entry`D3std9exception14__T7enforceTbZ7enforceFNaNfbLAxaAyamZb
+ 94
where the locking text writer is enforcing some condition.
(possibly that it received the correct amour of arguments)
Frame 2 is the enforce bailing out
Frames 1 is bailout() throwing a _new_ exception.
_d_newclass(exception)
frame 0 is the gc_malloc attempting to allocate the memory for
the exception.
and hits a
stop reason = EXC_BAD_ACCESS (code=1, address=0x0)
-> 0x10008d985: movq (%rdi), %rbx (rbx = *rdi)
null pointer somewhere.
your main function looks like
int main(string[] args)
{
writefln(...); // Double check whats going on here
...
return 0;
}
try
int main(string[] args)
{
try writefln(...); // Double check whats going on here
catch(exception e)
{
writeln("caught some exception"); // alternatively use
printf/puts if written also fails
}
...
return 0;
}
and you will see
caught some exception instead of the stack trace.
Are you profiling with an external profiler or using the compiler
to emit profile statistics?
My only guess is that there is a bug in the compiler's inserted
profiling code.
perhaps someone else will be able to help.
