I very much suspect that this is caused by the generated internal object file
names of a library or other generated identifiers that are assumed to be
unique, but clearly this is not guaranteed when building libraries in separate
build steps.
I tried to generate a small test on that suspicion some time ago, but it didn't
trigger a linker error then. I have figured it out now:
module ab;
struct AB
{
int a;
int len() { return (new AB).a; }
}
unittest
{
}
module ba;
struct BA
{
int b;
int len() { return (new BA).b; }
}
unittest
{
}
import ab;
import ba;
int main()
{
AB ab;
BA ba;
return ab.len() + ba.len();
}
now building with dmd 2.062:
dmd -lib -of"alib.lib" ab.d
dmd -lib -of"blib.lib" ba.d
dmd -c main.d
dmd main.obj alib.lib blib.lib
yields:

http://d.puremagic.com/issues/show_bug.cgi?id=9044 --- Comment #23 from Denis Shelomovskij 2013-03-14 18:29:41 MSK --- Ping. This is a dmd issue, not OPTLINK one. And the fact it is not a REGRESSION doesn't mean we should continue releasing dmd with it included as it even worse than a regression as it is triggered randomly. Personally I already suffer enough from OPTLINK and the fact dmd also produces corrupted object files looks too cruel. With all this words about language stability we have this issue which may accidentally brake build of every code base on every platform because of a any small code change. I worked on only two non-toy D executables for the last 6 month and both are [partially] blocked because of this. For now I abandoned the first project and have managed to juggle with files to "detrigger" this issue in second one. So I'm completely missing the point where are these issues with higher priority than this, abandoned, unvoted one? Probably I'm the most luckless D user who always suffer from these linking failures... -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---
