Contain the error message and the 2 files create by clang
Hello,
Doing a mistake in my program, I made clang++ segfault. Here is a simple sample
of it.
#include <iostream>
void dump()
{}
template <typename Data, typename Data2, typename... Datas>
void dump(Data&& data, Data2&& data2, Datas&&... datas)
{
std::cout << data << ":\t" << data2 << std::endl;
dump(datas..., datas...);
}
template <typename Data, typename Data2>
void dump(Data&& data, Data2&& data2)
{
std::cout << data << ":\t" << data2 << std::endl;
}
int main(int argc, char *argv[])
{
dump("cornealReflexion", 42.0, "cameraPos", 27.3f, "titi", 42);
return 0;
}
It segfault when instead of doing: dump(datas...); I do: dump(datas...,
datas...);
The full message and stacktrace is in the attachment files</pre>
