Comment at: lib/AST/ASTContext.cpp:8588
+ Expr *E = VAT->getSizeExpr();
+ if (E && VAT->getSizeExpr()->isIntegerConstantExpr(TheInt, *this))
+ return std::make_pair(true, TheInt);
----------------
`E && E->isIntegerConstantExpr`?
================
Comment at: lib/AST/ASTContext.cpp:8603
+ std::tie(HaveRSize, RSize) = SizeFetch(RVAT, RCAT);
+ if (HaveLSize && HaveRSize && LSize != RSize)
+ return {}; // Definite, but unequal, array dimension
----------------
The != will hit an assertion failure if LSize and RSize don't have the same
bitwidth.
