is it safe to generate profiles from multiple concurrent processes?

> std::fstream::in is not a type 

the error is indeed 
error: ‘in’ in ‘std::fstream {aka class std::basic_fstream<char>}’ does not name a type

btw  you have a spurious “;” before "|"

I think you are confusing the usage of “using” and “auto” keywords

this compiles

#include <fstream>
int main () {
auto && my_read = std::fstream::in;
std::fstream fs;
fs.open ("test.txt", my_read | std::fstream::out | std::fstream::app);
fs << " more lorem ipsum";
fs.close();
return 0;
}
