Just got the TDPL book and it's a great read! I learn best when typing
out the code myself, so I decided to make a single VisualD project and
put the different exercises in separate modules. I am having problems
with sort in std.algorithms - well, actually it appears to be a closure
problem when sort calls my delegate.
There shouldn't be any closure here, sort is not storing the delegate
pointer.
Here's a sample of the problem - in main.d I have
//------------------
module main;
import std.algorithm;
void main() {
uint[string] counts = [ "a":4, "b":5, "c":3, "d":1 ];
string[] keys = counts.keys;
sort!((a, b) { return counts[a] > counts[b]; })(keys);
}
//------------------
Alone this works just fine. But if I add another file called myalgs.d,
and put the following in it:
//------------------
module myalgs;
import std.algorithm;
//------------------
Then I get the following exception:
object.Error: Access Violation
----------------
C:\D\dmd2\windows\bin\..\..\src\phobos\std\algorithm.d(7112):
mainmain__T8sortImplS14main9__lambda3VE3std9algorithm12SwapStrategy0TAAyaZsortImpl
----------------
Steping through the code it appears that the Access Violation occurs
when accessing counts[a].
I am using DMD32 v2.059; my compilation command line looks like:
dmd -g -debug -X -Xf"$(IntDir)\$(TargetName).json"
-deps="$(OutDir)\$(ProjectName).dep"
-of"$(OutDir)\$(ProjectName).exe_cv" -map
"$(INTDIR)\$(SAFEPROJECTNAME).map" -L/NOMAP
I can't see any errors, I think this is worthy of a bug report, it's nice
and small and self-contained.
