Getting a CE, but not receiving any compiler output

[Stathol]

This is two issues in one.

The immediate issue:
I made a submission nearly an hour ago that failed with CE, but I still haven't received any compiler output. Supposedly this is sent by email. I also checked the submission status page just in case, but there's no output there, either. I've checked the spam folder, etc. (gmail), and can find no sign of an email from the UVa system. I did receive the registration emails, so I know my address is correct and I don't think Gmail is filtering it.

The secondary issue:
My code compiles just fine on my own system with g++ 5.2.1. Possibly relevant info:

Code: Select all

user@host:~/Documents/uva/105$ g++ --version
g++ (Ubuntu 5.2.1-22ubuntu2) 5.2.1 20151010
<snip>

Code: Select all

user@host:~/Documents/uva/105$ uname -a
Linux host 4.2.0-35-generic #40-Ubuntu SMP Tue Mar 15 22:15:45 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

And my compiler command:

Code: Select all

user@host:~/Documents/uva/105$ g++ -lm -lcrypt -O2 -pipe -DONLINE_JUDGE uva105.cpp

It even compiles with -Wall -Werror. I'm having a hard time imagining why it wouldn't compile on g++ 5.3.0. I don't want to jump to any conclusions, but the failure to provide any output makes me wonder if the whole build system is borked.

Well, the problem seems to have sorted itself out.

Shortly after I posted this, the whole site went offline. Eventually I stopped getting 5xx errors from the site, but I was still getting stuck in an infinite redirect loop. Eventually I discovered that this was due to something in my cookie(s) for this site. After clearing all *.onlinejudge.org cookies, everything seems to be back in working order.

I resubmitted the same file, and this time it came back AC. I don't know whether the spurious CEs were due to cookie corruption, or due to whatever caused the site outage (or whether the site problems caused the cookie corruption). In any case, I guess it's "fixed".
