Summary: clang++ crashes with -fshort-enums
Product: clang
Version: trunk
Platform: Macintosh
OS/Version: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: Frontend
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
I have tried to reduce the problem as much as I could:
$ cat clangbug.cc
enum E { VALUE_1 };
template <typename T>
static void
foo()
{
(void)sizeof(T);
}
template <typename T>
struct A {};
template <E Enum>
struct B : A<B<Enum> > {};
static void
bar()
{
foo<B<VALUE_1> >();
}
$ g++ -fshort-enums -g clangbug.cc -c
$ clang++ -fshort-enums -g clangbug.cc -c
Assertion failed: (I.getBitWidth() == Info.Ctx.getIntWidth(E->getType()) &&
"Invalid evaluation result."), function Success, file ExprConstant.cpp, line
944.
( Many lines of backtrace )
