I get (see e.g. submission spoj.pl/error/5335250) this weird compilation error.
{standard input}: Assembler messages:
{standard input}:3: Fatal error: can't write /home/Jw2bFh/cc9VC8Sf.o: No space left on device
{standard input}:3: Fatal error: can't close /home/Jw2bFh/cc9VC8Sf.o: No space left on device
The source file is 3k and the code generated on my machine is 13k in size, so nothing that could really eat up much of disk space.
Moreover, I see a lot of other people failing C++ submissions with compilation errors tonight (though a few get past the compilation hurdle)
