Crash log
Another random-testing crash, we get this one with either
`-flto=thin --coverage` or `-flto=thin -fsanitize=undefined`.
$ cat bz157339.cpp
struct X { ~X() {}; };
int main() { X x; }
$ clang bz157339.cpp -flto=thin --coverage
clang-4.0:
/home/probinson/projects/llvm-org/trunk/llvm/include/llvm/IR/ModuleSummaryIndex.h:432:
llvm::GlobalValueSummary* llvm::ModuleSummaryIndex::getGlobalValueSummary(const
llvm::GlobalValue&, bool) const: Assertion `GV.hasName() && "Can't get
GlobalValueSummary for GV with no name"' failed.
Full crash log attached. Diffing this one and the one with ubsan
didn't show any significant differences.</pre>
