Summary: Sample code works on GDC but fails with DMD
Product: D
Version: D2
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: DMD
AssignedTo: nobody puremagic.com
ReportedBy: russel winder.org.uk
PDT ---
The code:
import std.algorithm ;
import std.range ;
import std.stdio ;
import core.thread ;
int main ( immutable string[] args ) {
auto threads = array ( map ! ( ( int a ) {
void delegate ( ) f ( ) {
return delegate ( ) { writeln ( a ) ; } ;
}
return new Thread ( f ) ;
} ) ( iota ( 10 ) ) ) ;
foreach ( t ; threads ) { t.start ( ) ; }
foreach ( t ; threads ) { t.join ( ) ; }
return 0 ;
}
compiles and runs as expected when using GDC on Linux:
Using built-in specs.

I am just going to point out that gdc is on 2.057 release. And my best
assumption would be this would be a library bug, not a compiler.

There are related two issues.
1. The implementation of core.thread.Thread class was hidden by adding
hand-made di file in 2.059. It hides actual class members with 'void[N] data'.
2. std.traits.hasIndirections doesn't define its behavior against void[N] type.
I think hasIndirections template should return true for void static array
types, because void data *may* have some indirections - it's conservative way.
But I'm not sure.
I am just going to point out that gdc is on 2.057 release. And my best
assumption would be this would be a library bug, not a compiler.
Yes, this is druntime or Phobos issue, not compiler's.
I'll change 'Component' from dmd to Phobos.
