Where can I find what this exit code means?

I have process (A) that calls program (B) using clib system(). Sometimes program (B) returns with exit code 721035 and AIX kills process A. This is random and I would like to figure out what the exit code means and why it happens.

Here is a dbx stack trace:

As you can also read here, this is probably a defect of the compiler you use. During the default optimization level it might generate incorrect code, making your application to fail and exit with 721035.

You can try to resolve this problem by selecting a lower optimization level during compilation. The default optimization level is -O2, so you can try compiling your code with -O1 or -O0.

The permanent solution (as stated in the link above) is to apply the the May 2011 PTF to your system.

Thanks, I've seen that posting, along with the JVM one with the same exit code. Any idea if we can attach any meaning to the exit code? So far I could not find sysexits.h that gives a hint. –  Derick Schoonbee Nov 28 '11 at 16:56
@DerickSchoonbee 721035 = 0xb008b. This looks like a value returned by waitpid and friends, with a status of 0x8b. That status would be returned by a shell which detected that a program terminated with signal 0xb=11, which on many unices is SIGSEGV. If my interpretation is correct, I don't know what the 0xb0000 part indicates. –  Gilles Nov 28 '11 at 17:42
