I cant find mistakes. Actually, the correct comment here would have been, "I can check .size() later and see I reserved too little. I can find mistakes" > vector v; > v.reserve(100000); > //non check emplace_back for 100001 times > This program will collapse. And I can know I've made mistake here. And here it is ".size() is still the same, so I don't know how many emplace_back I've made. There may have been a silent buffer overrun that didn't trigger any visible effects while testing. I can't find mistakes". -- Thiago Macieira - thiago (AT) macieira.info - thiago (AT) kde.org Software Architect - Intel Open Source Technology Center -- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.
