when the program ran alone without redirection or pipe line, the output went to screen which was line buffered so you can see it before it died. All the other scenarios you had later involved buffering of larger amount of data. Due to the sudden death of the program the output was lost.
You can run the program under a tty program or modify the source code to make it line buffered or flush the output.

Hi ,
Working on AIX 4.3. An internal error from my apps engine suddenly causes the engine to die. During this time i do notice a core file being dumped in the directory from where I try to re-start my engine.
Q is how does one read this core file, or I should say 'what is this core file'?

CRASH(8) BSD System Manager's Manual CRASH(8)
NAME
crash -- examine and debug system images
SYNOPSIS
crash [-M core] [-N kernel]
DESCRIPTION
The crash command is used to examine and debug system images.
If run without any arguments, crash operates on the running system.
The options are as follows:
-M core Operate on the specified crash dump instead of the default /dev/mem. Crash dumps should be from the same version of the system
and same machine architecture as the running version of crash, and must be uncompressed.
-N kernel Extract the name list from the specified kernel instead of the default /dev/ksyms.
The command syntax used by crash is the same as the in-kernel debugger. See the ddb(4) manual page for more information.
Operations and facilities that require a running system, such as breakpoints, are not supported by crash.
crash does not provide pagination. However, by using the pipe symbol, output may be sent to commands available from the shell. For example:
crash> ps | more
crash> ps | grep ioflush
SEE ALSO
ps(1), vmstat(1), ddb(4), pstat(8)
HISTORY
The crash command appeared in NetBSD 6.0.
