// a.d
import b;
void main()
{
    new A();
}

// b.d
class A
{
    protected this(){}

}


When these source codes are compiled with dmd trunk r628, dmd outputs a correct
error message and crashes.


dmd a b
a.d(4): Error: class b.A member this is not accessible <-- crash!! The cause of the crash is an access to the null pointer as shown below. // toctype.c ... type *TypeFunction::toCtype() { type *t; if (ctype) return ctype; if (1) { param_t *paramtypes; tym_t tyf; type *tp; paramtypes = NULL; size_t nparams = Parameter::dim(parameters); for (size_t i = 0; i < nparams; i++) { Parameter *arg = Parameter::getNth(parameters, i); tp = arg->type->toCtype(); if (arg->storageClass & (STCout | STCref)) { // C doesn't have reference types, so it's really a pointer // to the parameter type tp = type_allocn(TYref, tp); } param_append_type(&paramtypes,tp); } tyf = totym(); t = type_alloc(tyf); t->Tflags |= TFprototype; if (varargs != 1) t->Tflags |= TFfixed; ctype = t; t->Tnext = next->toCtype(); // <<<<<<<<<<<<<<<< next is null t->Tnext->Tcount++; t->Tparamtypes = paramtypes; } ctype = t; return t; } ... -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

I cannot reproduce this. For me on Windows, it prints the error message, but
does not crash. Perhaps the test case is slightly wrong?

Oh really? Now, I performed it with dmd r712, druntime r398, and phobos r2092. dmd crashed again within an error message. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

This is a silly one!
This only appears in debug mode, it because Walter accidentally left a call to
"halt()". access.c, line 256.

This ICE can never occur in a release version of the compiler.
