Summary: Null pointer reference

In the InitListExpr::InitListExpr in Expr.cpp I'm seeing a call to this
function from InitListChecker::getStructuredSubobjectInit where the initExprs
parameter is 0, causing an assertion failure in the collections stuff starting
from this line (approx. Expr.cpp:741):
InitExprs.insert(C, InitExprs.end(), initExprs, initExprs+numInits);
The caller is explicitly passing 0 in the third argument:
InitListExpr *Result
= new (SemaRef.Context) InitListExpr(SemaRef.Context,
InitRange.getBegin(), 0, 0,
InitRange.getEnd());
so it seems there is an arguments mismatch or logic error. To work-around, I
just check for a null pointer and avoid the first call above, but because I'm
compiling a huge file with lots of errors, I don't know if it's related to
improper error recovery or not, though it seems this problem happens before the
first error is emitted.
If the above is not sufficient, I can take the time to try to narrow down a
test case.
