Do there exist any RE reports?

Post by tjocko » Fri May 21, 2010 7:43 pm

Quote from "How to understand the Online Judge answers":
Runtime Error (RE): Your program failed during the execution (segmentation fault, floating point exception...). The exact cause is reported to the user.

How is the cause of RE reported to the user? I can not find any hints of the actual cause of RE. Where can I find the report?

(N.B. I do Java submissions.)

I haven't used the judge for a while, but previously they only reported which Unix signal killed your program. E.g. SIGSEGV, SIGFPE (floating point exception), SIGABRT (call to abort()), etc. But JVM doesn't crash in this way, so RE means just that JVM exited with a non-zero exit code. No other details of the error are given. Probably because 1) it could leak too much information about test data, and 2) real ICPC contests also don't give any details. So you shouldn't expect to see a stack trace.
