Bug ID: 21488
Summary: Assertion failed: (isa<clang::sema::LambdaScopeInfo>(
FunctionScopes[FunctionScopes.size() - 1]) && "The
function on the top of sema's function-info stack must
be a lambda")
Product: clang
Version: trunk
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: C++14
Assignee: unassignedclangbugs at nondot.org

Classification: Unclassified
The following code causes Clang r221326 to segfault:
------------------------------------------------------------------------------
#include <tuple>
std::tuple<int> id(std::tuple<int> x) { return x; }
template <typename Xs>
auto depth4(Xs xs) {
int s;
auto capture = [=](auto _) { _(xs), s; };
capture(id);
}
template <typename Xs>
auto depth3(Xs xs) {
depth4(xs);
}
template <typename Xs>
auto depth2(Xs xs) {
depth3(xs);
}
template <typename Xs>
auto depth1(Xs xs) {
depth2(xs);
}
int main() {
std::tuple<int> xs;
depth1(xs);
}
------------------------------------------------------------------------------
Note that the code will also _sometimes_ compile, and other times Clang will
simply stay stuck at 100% CPU usage until I kill it. Doing even slight
modifications like removing one depthN function seems to make Clang happy,
so I wasn't able to reduce the example more than that.
When it segfaults, the exact output is:
