Reduced further:
-----------
void one(T)(T t, size_t ln = 0)
{
    pragma(msg, "one: ", T.stringof);
    two(t);
}

void two(T)(T t)
{
    pragma(msg, "two: ", T.stringof);
}

alias T = void delegate();

void main()
{
    void func() @system { __gshared int x; ++x; throw new Exception(""); }
    one(&func);
}
-----------

Commenting out the `alias T` line makes the problem go away.

Current investigation seems to be pointing to an ambiguity in the string table.
Still investigating further to narrow the problem down further.
