Bug ID: 16854
Summary: clang crash when doing tuple magic
Product: clang
Version: 3.3
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++11
Assignee: unassignedclangbugs at nondot.org
Reporter: janezz55 at gmail.com
CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
Classification: Unclassified
I get a crash while compiling this code:
template <std::size_t O, class C, std::size_t ...I>
inline C get_tuple_arg(lua_State* const L, indices<I...> const)
{
C result;
[](...){}((
lua_rawgeti(L, O, I + 1),
std::get<I>(result) = get_arg<-1,
typename std::tuple_element<I, C>::type>(L),
lua_pop(L, 1),
0)...);
return result;
}
The lambda trick can be omitted and clang will still crash.
The complete code is here:
https://code.google.com/p/lualite/
gcc groks the code without issue.
