memory leak ?

[Peter Van Osta <pvosta unionbio-eu com>]

Hi,

I allocate a structure "EzxRdrImgObj" and an "embedded" octet sequnce
"EzxRdrImgBuf" on the ORBit server side and return the structure to the
client where I transfer the content of the sequence to an "image" buffer
and afterwards relase the sequence with "CORBA_free( img->data._buffer
)", however freeing the structure (retunr value) with CORBA_free gives
me a segmentation violation. If i use "free" it dos not crash, but it
doens't seem to free the meory either. I have pasted the source code of
the client routine below.

I thought that sequentialy freeing first the embedded octet sequence and
then the structure itself would do the job ? I am now testing the
behaviour of the sytem, so not everything has been completed, but the
transfer of image data should work ?

The image reading routine in the server:
impl_EzxS_Srvr_ReadImage(impl_POA_EzxS_Srvr * servant,
EzxS_EzxRdrDatastoreObj * Ezxstrg, CORBA_char ** message,
CORBA_Environment * ev)

I set "release" to FALSE in the server for the sequence has to be
returned to the client for readout before being released in the client.

e.g.:
typedef sequence<octet> EzxRdrImgBuf;

struct EzxRdrImgObj {
        char name[64];
        EzxRdrImgBuf data;
        short type;
        long width;
        long height;
        long depth;
        long slice;
        short axis;
        long clut;
};


Best regards,
