--- Comment #4 from Walter Bright <bugzilla at digitalmars.com> ---
This is apparently caused by the code in e2ir.d:

elem *buildArrayBoundsError(IRState *irs, const ref Loc loc)
{
    if (irs.params.checkAction == CHECKACTION.C)
    {
        return callCAssert(irs, loc, null, null, "array overflow");
    }
    if (irs.params.checkAction == CHECKACTION.halt)
    {
        return genHalt(loc);
    }
    auto eassert = el_var(getRtlsym(RTLSYM_DARRAYP));
    auto efile = toEfilenamePtr(cast(Module)irs.blx._module); ***
    auto eline = el_long(TYint, loc.linnum);
    return el_bin(OPcall, TYvoid, eassert, el_param(eline, efile));
}

Note that it gets the filename from _module rather than loc. I believe it is
this way to stop the redundant generation of filename strings into the object
file. The previous function filelineFunction() gets it fro the loc.
