I wrote Topcoder SRM 450 Div1 medium's solution and submitted and ran system test, I got segmentation fault on some case. I ran system test again and again, every time I ran it, segmentation fault appeared on different case on same solution. (Once I got RE on test 3, but another time I got AC on test 3, but I got RE on test 27... etc)
ryo_issy also say that he got same trouble on SRM573 Div1 medium...
What is happening?
Delta003 and I have been solving some practice SRM and TCHS competitions and we also get segmentation fault on random test cases.
Me too — http://codeforces.net/blog/entry/7015
I've got a problem too. I get segmentation fault on both SRM573 Div2 easy and SRM573 Div2 medium on random cases. Something weird is happening.
I am getting the same error for SRM 413 Div2 Hard.
Yeah, they are complaining about the same thing on TopCoder forums. Seems like a system bug.
Its my fault (or segfault XD), sorry guys :/
Now this trouble has disappeared. Thank you!
I had the same problem in a contest in codechef. I reached out to them via mail, and apparently it was an array out of bounds. They said that array out of bounds in a C style array is not very strict and sometimes it goes undetected. And hence using vectors or std::array is a better option if you think there might be an array out of bounds
I tried to report it as a bug. Here is a bug report response
