Using std.algorithm.sort(a,b,c,d,e) I get the error message :
core.exception.AssertError@C:\dmd\windows\bin\..\..\src\phobos\std\algorithm.d(1
0350): Predicate for isSorted is not antisymmetric. Both pred(a,
b) and pred(b,
a) are true for a=Tuple!(float, int, uint[], int,
uint[])(-7.56963e-05, 17, [585
105407, 512], 1041, [2732589055, 0]) and b=Tuple!(float, int,
uint[], int, uint[
])(-7.56963e-05, 17, [2732589055, 0], 1105, [585105407, 512]) in
positions 25182
and 25183
I am using the default predicate so is it a bug?
