Bug ID: 26444
Summary: [Regression] Clang crashes on structs with large
alignment
Product: clang
Version: 3.8
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Frontend

Hi,
Clang 3.8 (and trunk) crashes on the following test case, but clang 3.7.1 works
fine.
$ cat align.cc
struct A {
A();
} a __attribute__((aligned(0x10000)));
$ clang --version
clang version 3.9.0 (trunk 259447)
Target: x86_64-unknown-linux-gnu
$ clang -S -o - align.cc
clang: Address.h:32: clang::CodeGen::Address::Address(llvm::Value*,
clang::CharUnits): Assertion `(!alignment.isZero() || pointer == nullptr) &&
"creating valid address with invalid alignment"' failed.
Could someone take a look?
