Bug 1010 – Abstract class template does not compile when parametrized with char[]

abstract class Foo(char[] bar) { } int main(char[][] args) { return 0; } Fails to compile with the error message: hello.d:1: variable hello.bar abstract cannot be applied to variable :: === Build finished: 1 errors, 0 warnings === While this works: template Foo(char[] bar) { abstract class Foo { } } int main(char[][] args) { return 0; }

Added to DStress as http://dstress.kuehne.cn/run/t/template_class_20_A.d http://dstress.kuehne.cn/run/t/template_class_20_B.d

This also happens with int parameters and probably with other types too.

*** Bug 2236 has been marked as a duplicate of this bug. ***

Example and DStress test cases compile in D1.041. The DStress test cases fail in D2, because the template parameter is declared as a char[] rather than a string. C:\> dmd template_class_20_A.d template_class_20_A.d(17): template instance Foo!("abc") does not match template declaration Foo(char[] bar) template_class_20_A.d(17): Error: Foo!("abc") is used as a type template_class_20_A.d(17): class dstress.run.t.template_class_20_A.Bar base type must be class or interface, not void The following code compiles, should this bug be marked as a DStress issue? abstract class Foo(string bar) { } class Bar : Foo!("abc") { } int main(char[][] args) { return 0; }

No. DStress was only developed for D1. It's never been ported to D2. You can safely close this bug.

(In reply to comment #5) > No. DStress was only developed for D1. It's never been ported to D2. Moreover, if it had, it would certainly not have been completely changed into a D2 test suite, but have some built-in distinction between D1 and D2 testcases. But still, the testcases here and in DStress WFM (1.042 Win).
