Application crash in exit ()

>here is what is installed: # Bundle(s):

This lumps all of the patches into a bundle so we can't see the aC++ runtime patches.
You would probably need to use:
swlist -l patch "PHSS_*" | grep aC

>I will ask the customer to upgrade but to be honest I'm a bit pessimistic.

Well, it does work on your system. :-)
Other than the patch level, what is different on the customer's system? The same application but different data?
Is there a trivial way to get into your application and then exit, so you can see if that path fails?

Hi, all:

I meeting the same problem on our system, it coredump on last line of our program "return 0",

$ gdb -c core
Core was generated by `SimpappClient'.
(gdb) where

Does the problem is solved? If it does, how did you guys slove it? Thanks.

Here is my version of acc

$ /usr/sbin/swlist -l patch "PHSS_*" | grep aC
# PHSS_30414                            1.0            aC++ Runtime (IA: A.05.56, PA: A.03.50)
# PHSS_32511                            1.0            HP aC++ Compiler (A.03.63)

This could occur if you call atexit(3) and you have unloaded the shlib that contains the function.

This is 6+ years old.

Did you mean that, I have unloaded the shlib that contains function __cxxTerm_body, then I call atexit(3) , so it cordump?

>I have unloaded the shlib that contains function __cxxTerm_body

No, you have unloaded the atexit registered function that __cxxTerm_body was going to call.

Basically shouldn't be using atexit(3) in C++, especially if you have shlibs.
