Bug ID: 22238
Summary: Clang crashes when bitfield-width contains a
functional cast expression for copy-constructing a
record
Product: clang
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]

consider:
extern "C" {
struct T {
char c;
} a;
struct B {
x : T(a);
};
}
we diagnose with:
t.cpp:6:3: error: unknown type name 'x'
x : T(a);
before crashing with:
lib/AST/ExprConstant.cpp:8565: llvm::APSInt
clang::Expr::EvaluateKnownConstInt(const clang::ASTContext&,
llvm::SmallVectorImpl<std::pair<clang::SourceLocation,
clang::PartialDiagnostic> >*) const: Assertion `Result && "Could not evaluate
expression"' failed
