Some more imput: Problem (1) is related to getline. I prepared this minimal
example after disecting a program that parses a text file which aborted under
cygwin (despite it worked well compiled with g++-7 under ubuntu).
Thanks for the patch for problem (2) Ken!

Thanks so much Jon!
I have noticed a couple of issues with g++-7.
1)
#include <string>
#include <iostream>
#include <sstream>
int main()
{
std::string Str;
std::stringstream ss("hello");
std::getline(ss,Str);
std::cout << Str;
return 0;
}
Compiling the above program with:
g++ -g -std=c++17 foo.cpp
Compiles just fine, but aborts when running it.
Running it with gdb:
Program received signal SIGABRT, Aborted.
0x6326126a in cygstdc++-6!_ZNSs7reserveEj () from /usr/bin/cygstdc++-6.dll
The program works fine if compiled with -std=c++14.
2)
This program fails to compile (it also failed with g++-6).
#include <shared_mutex>
int main() {}
