How do I find out what that means?
Many return codes have a meaning in the linux documentation:
http://www.tldp.org/LDP/abs/html/exitcodes.html#EXITCODESREF
(it lists them as unsigned, but you got a signed result. 128 ==
-1, so -11 falls under the 128+ section in that table)
-11 means it exited with signal 11. Do "man 7 signal" in linux to
get the signal documentation overview. One of the lines there is:
SIGSEGV 11 Core Invalid memory reference
Signal #11 is segmentation fault.
Since you're a D newbie, I'm guessing you made the mistake of
forgetting to new a class before using it:
class Foo {}
void main() {
Foo foo;
foo.something(); // this will segfault, killing the program
}
That's different than C++, D's classes are more like Java. You
need to:
Foo foo = new Foo();
or
auto foo = new Foo();
so it isn't a null reference.
