Here's some code to create a symbol name that is longer than 64kB:

module test;

template TypeTuple(TList...)
{
    alias TList TypeTuple;
}

 property void assertCTFEable(alias dg)()
{
    static assert({ dg(); return true; }());
    dg();
}

alias TypeTuple!(0,1,2,3,4,5,6,7,8,9) T10;
alias TypeTuple!(T10,T10,T10,T10,T10,T10,T10,T10,T10,T10) T100;
alias TypeTuple!(T100,T100,T100,T100,T100,T100,T100,T100,T100,T100) T1000;

string to_string(string s) { return s; }

void foo()
{
    assertCTFEable!(
    //auto dg = (
    {
    foreach (i; TypeTuple!(T100,T100,T100,T100,T100,T100,T100,
                           T10,T10,T10,T10,T10,T10,
                           0))
    {
        assert(to_string("hello world") ==
               to_string("hello world"));
    }
    });
}

void main() {}

build with "dmd -g -m64 test.d" to get

test.obj : fatal error LNK1103: debugging information corrupt; recompile module
--- errorlevel 1103

or with a slightly longer symbol:
LINK : fatal error LNK1318: Unexpected PDB error; RPC (23) '(0x000006BA)'
--- errorlevel 1318

This is a reduced test case from the std.string unittests.
