Bug ID: 36381
Summary: Crash in NonNullParamChecker /
clang::ento::RangedConstraintManager::assumeSymUnsuppo
rted()
Product: clang
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: Static Analyzer
Assignee: dcough...@apple.com
Reporter: ale...@google.com
CC: ekarpen...@apple.com, llvm-bugs@lists.llvm.org
Here's a test case I reduced manually from the output of creduce:
class C {};
void f(C i) {
auto lambda = [&] { f(i); };
typedef decltype(lambda) T;
static char *p;
T **pfn = static_cast<T **>(static_cast<void*>(&p));
*pfn = new T(lambda);
(**pfn)();
}
