Hello,On Cygwin 2.8.1 x86_64, I've found that g++ std:map initializing may raise segmentation fault. The binary compiled with cygwin-devel-2.8.0-1 does not raise segmentation fault even if on Cygwin 2.8.1 x86_64 environments. So I suspect cygwin-devel-2.8.1-1 is the cause. Here's sample code for reproduce. ``` // foo.cc // g++ -std=c++11 foo.cc #include<iostream> #include<map> std::map<int, int> m { { 1, 1}, { 2, 2} }; int main () { std::cout << "Hello World!" << std::endl; } ``` I've reproduced it on both Windows 7 64 bit and Windows 10 64 bit. ``` $ ./a Segmentation fault (core dumped)
I've just checked that the problem occurs with the 2017-06-20 snapshot but not with the 2017-06-06 snapshot. I don't have time right now to do a further bisection, but I can probably do it later today or over the weekend if no one beats me to it.
