Problem with Codeforces C++ 11 compiler?

Revision en2, by tenshi_kanade, 2016-02-03 02:24:40

I've recently come across a very strange problem using C++ 11.

I submitted a solution for problem 620C - Pearls in a Row using unordered_map and got TLE, then I submitted the exact same solution using map (it's supposed to be slower: O(1) amortized VS O(logN) per operation) and it got Accepted with 280 ms.

Submission with unordered_map: 15756653

Submission with map: 15759645

Is this some kind of problem with the C++11 compiler used here on Codeforces? Anyone got a clue?
