Bug ID: 49720
Summary: SIGSEGV in recursive function template with generic
lambda argument
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++
Assignee: [email protected]
Reporter: [email protected]

The following translation unit
```
template<typename Outer>
auto recurse(Outer outer_lambda) {
outer_lambda(0);
auto lambda = [](auto) {};
recurse(lambda);
}
void start() {
recurse([](int) {});
}
```
should hit the template instantiation depth and fail to compile. Instead, the
compiler crashes with a SIGSEGV, even with assertions enabled.
See it live: https://godbolt.org/z/6q7vbx8qb
It looks like this was introduced in clang 4.0.0
