Bug ID: 20717
Summary: assertion failure assigning to immutable generic
lambda init-capture
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++1y
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
This testcase:
auto x = [i = 0](auto n) { return i += n; }(1);
... causes clang to assert in C++14 mode:
clang-3.5: include/llvm/Support/Casting.h:95: static bool
llvm::isa_impl_cl<clang::Decl, const clang::DeclCo
ntext *>::doit(const From *) [To = clang::Decl, From = const clang::DeclContext
*]: Assertion `Val && "isa<> used on a null pointer"' failed.
The bad cast<...> call on a null pointer is here:
