Hi,
from https://www.spoj.pl/tutorials/USERS/:
RE - runtime error - your program was compiled successfully, but it exited with an error; possible codes are:
- SIGSEGV (signal 11) - most common, "segmentation fault" - index out of array, etc.
- SIGXFSZ (signal 25) - "output limit exceeded"
- SIGFPE (signal 8) - "floating point error" - like division by zero, etc.
- SIGABRT (signal 6) - raised by the program itself; C++ STL does it under some conditions
- NZEC (non-zero exit code) - helps telling crash from WA with interpreted languages
- other - there are other signals which can cause program to terminate, all remaining are shown as other
