--- Comment #3 from so61pi.re at gmail dot com --- My current version of GCC is 5.1.0 on Windows, but I also tested on Linux with same GCC version, and it produced the same bug, which printed random value like Daniel Krügler have showed. Apparently, this bug is fixed in gcc HEAD 6.0.0 20150619 (experimental). My command line was: g++ -std=c++14 main.cpp -o main.exe And here is the output of 'g++ -v' on my system: Using built-in specs.
