libc.2 error from my application

[Pushpa Kumari K.H]

Hi,

I have used the below machine & compiler for Qt installation.

Compiler aCC: HP ANSI C++ B3910B A.03.70
OS HP-UX B.11.11 U 9000/785 2015658734 unlimited-user license
Qt 3.3.7

and Qt is installed successfully with these :

./configure -platform hpux-acc-64 -thread stl -qt-zlib

Now my application is not running I edited it with the debug option and try to debug from wdb.
It tells

main (argc=0, argv=0x800003ffff7f0b10) at /home/pushpa/BViewNG/Test/BViewNG_3.3.2/Viewer/main.cpp:125

Program received signal SIGABRT, Aborted
si_code: 0 - .
0x800003fffdae628c in kill+0x2c () from /usr/lib/pa20_64/libc.2

Could you please help me with this.

Thanks and Regards,
Pushpa.

This is the standard way a process that calls abort(3) terminates. You need a full stack trace.

Hi Dennis Handly,

This is the full stack trace I found out :

>This is the full stack trace I found out:

Please try again. Use the "bt" command. I see something like a stacktrace but it should look like #0... #1... and back to main or the thread start.

[Pushpa Kumari K.H]

Hi Dennis,
I did bt and this is the error stacktrace :

Could you please help me further as I am new to this.

Thanks, this is more helpful.

1) You are using threads and you didn't compile EVERYTHING with -mt.

2) Of course there are other things string::replace can throw, depending on the parms:
x.replace(large1, large2, "", large3, large4, large5)

If you look at string.cc:400 it appears you don't have the -mt case but your parms are bad so it is throwing out_of_range. Either gdb is broken and printing addresses instead of values or you have bad parms. You could compile with +d to prevent inlining so you can see what you are calling.

[Pushpa Kumari K.H]

Hi Thanks,

I hv updated compilation with the options -mt and +d, even now i get the same error, this application in windows works , I am not getting anything about this in unix.

In windows the statment
MainWindow *mw = new MainWindow;

allocates memory and goes to the constructor, here i cannot makeout the allocation of memory or initialization.

Could you please help me further in debugging this please.

Pushpa

[Dennis Handly]

>I hv updated compilation with the options -mt and +d, even now I get the same error,

Are you sure you have the same number of frames and the same functions? Did you recompile libBViewNGScriptEngine.sl?

Your MainWindow constructor was calling the ScriptEngine constructor, which is calling the
ScriptEngine::VariableString constructor which was calling string::replace.

Do you have libBViewNGScriptEngine.sl compiled with -mt, -g and +d?

[Pushpa Kumari K.H]

Hi,
I checked with the library file it is compiled with -g, -mt,+d and I get this stracktrace :

Ok, you need to look at the string::replace call in frame 10, scriptEngine_variables.cpp:959 and check the parms.
What was the VariableString trying to do??
Then go to frame 9 and see why __pos, __n and __s seem to have bad values.
