Standard Unix exit codes are defined by sysexits.h, as another poster mentioned. The same exit codes are used by portable libraries such as Poco - here is a list of them:

A signal 11 is a SIGSEGV (segment violation) signal, which is different from a return code. This signal is generated by the kernel in response to a bad page access, which causes the program to terminate. A list of signals can be found in the signal man page (run "man signal").
