Hi,

I was playing a bit with templates in D and found the following link error when trying to compile.

$ dmd list.d
gcc list.o -o list -lphobos -lpthread -lm
list.o(.gnu.linkonce.t_D11collections4list6List_i4List5_dtorFZv+0x35): In
function `_D11collections4list6List_i4List5_dtorFZv':
: undefined reference to `_d_delmemory'
collect2: ld returned 1 exit status
--- errorlevel 256

The problem is related to a delete statement inside the destructor of a class template. I am trying to manually clean the resources used by a dynamically linked list (yes, I know the GC can do it for me). The problem occurs in line 72 (code atached).

If I remove the code inside the destructor, the testing program compile, link and run fine.

Thanks in advance,

Bruno.

Sorry, the problem is in line 102.
