even worse: the link fails if the template is in a library and the library is
not compiled with unittests:
import std.stdio;
void main()
{
writef(\n);
}
dmd -unittest test.d

Error 42: Symbol Undefined _D3std6format15__unittest_failFiZv
--- errorlevel 1
Strangely, the relased phobos.lib is compiled with unittests, while the
makefile does not pass -unittest. So this does only show up when I compile
the runtime library myself.

Here's a workaround: similar to the assert handling, generate the unittest_fail
function whenever there is a template in the module:
Index: template.c
===
--- template.c(revision 632)
+++ template.c(working copy)
@@ -429,6 +429,13 @@
sc-module-toModuleAssert();

+if (/*global.params.useUnitTests */ sc-module)

+// Generate this function as it may be used
+// when template is instantiated in other modules
+sc-module-toModuleUnittest();

/* Remember Scope for later instantiations, but make
* a copy since attributes can change.
