Package: g++-6 Version: 6.2.0-13 Severity: normal Dear Maintainer,
This program fails: ``` c++ #include <cstdint> int main() { uint64_t toto = 800*16'800'000; // *should* be 10'080'000'000 return 0; } ``` when compiled with: ``` make all: g++ -Wall -std=c++14 main.cpp -o main.out ``` But it does work if I make the calculation myself. g++ issued a warning (-Woverflow) and there was an overflow. Expected result is 10'080'000'000 which fits in uint64_t, but got an overflow instead.
