Segfaulting in createTypeInfoArray(): exps[i] is null.
Applies to DMD0.175 and later, including both D2.036 and D1.051.
---
void foo(int,...) {}
void bar(){
foo();
}
---
arr.d(4): Error: function arr.foo (int _param_0,...) is not callable using
argum
ent types ()
arr.d(4): Error: expected 1 function arguments, not 0
segfault
Doesn't happen with C-style variadics.

CAUSE: if not enough arguments, tries to create a negatively-sized type info
array!
PATCH: expression.c, line 802 (DMD2 svn 241), at end of functionArguments():
---
// If D linkage and variadic, add _arguments[] as first argument
-if (tf-linkage == LINKd tf-varargs == 1)
+if (tf-linkage == LINKd tf-varargs == 1 arguments-dim = nparams)
{
Expression *e;
e = createTypeInfoArray(sc, (Expression **)arguments-data[nparams],
arguments-dim - nparams);
arguments-insert(0, e);

struct Node {
size_t _left;
Node* left() {
return cast(Node*) (_left 1);
}
bool useLeft() {
return left is null;
}
}
Result:
Internal error: ..\ztc\cgelem.c 3387
This one is really hard to reproduce. If you change this test program in even
very small ways, it's no longer reproduced.
