[Dpcl-develop] [Dpcl-user] DPCL 3.2.2: Core when trying to load a 64-bit probe module.

[Albert F. <al...@us...>]

Jordi, The only change between 3.2.0 and 3.2.1 in this area is that we
added the module magic number check, we only support 32 bit application in
aix 4.3.3, and the 'new 64 bit object format' in AIX 5.1.

You need to compile the module and 64 bits application  with '-q64
-qlargetype' compiler flag in order to create the new format.

As for the core file, you need to catch the module's exception.

    try {
         pm=ProbeModule( "full-path-name-of-the-64-bit-probe-module" );
    } catch (AisStatus sts) {
     ....
    }

 Hi,

 some days ago, we have upgraded our system to DPCL 3.2.2 and we detected
 a problem when using this new version.

 When I try to create a 64-bit DPCL probe module I get an "Abort (core
dumped)".

 The code that fails do:

        pm = ProbeModule( "full-path-name-of-the-64-bit-probe-module" );

 where we are creating the ProbeModule object to load it within the target
 application.

 It is important to note that for 32-bit module/applications it works well.

 I have checked with DPCL 3.2.1 and 3.2.0:
      - 3.2.0 works well with 32 and 64 bits  module/applications
      - 3.2.1 have the same behavious than 3.2.2

 The stack call of core file is:

    pthread_kill(??, ??) at 0xd0014bf8
    _p_raise(??) at 0xd0013fac
    raise.raise(??) at 0xd017618c
    abort.abort() at 0xd016f8c8
    myabort__3stdFv() at 0xd12109f4
    terminate__3stdFv() at 0xd1210a74

    ProbeModuleInt.ProbeModuleObj(const char*)(0x2001a448, 0x2ff21188),
line 330 in "ProbeModuleInt.C"
    ProbeModuleInt.add_entry(const char*)(0x2001fec8, 0x2ff21188), line 527

    unnamed block $b870, line 68 in "ProbeModule.C"
    ProbeModule.ProbeModule(const char*)(0x2ff21164, 0x2ff21188), line 68

    main(0x3, 0x2ff228e8, 0x2ff228f8) at 0x1000a9b0


 Did somebody had the same problem ? Any clue ?

 Regards,
 Jordi.
