from cxmldocument::load(char*)

m_doc = (char*) malloc(m_size); //***********
if (!m_doc)
{
m_size = 0;
fclose(hfile);
return -2;
}

if (fread(m_doc, m_size, 1, hfile)<=0)

m_doc = 0;
m_size = 0;
fclose(hfile);
return -3;
}

malloc and delete mixed. baaad. and the buffer is not deleted in the destructor => memleak...

[questor/fused]

i thought about that a bit and found the answer by myself:
there's a malloc, because "new" would've needed another import-function (??2@yapaxi@z from msvcr71) and that's not included in the msvcr71-emulation-layer!

and mixing malloc and delete seems to break the whole structure (when you include the import-functions into the emu-layer).

oh, and not including the functions into the emulayer the delete in the function does nothing, because it's an unemulated import => dummy-import => do nothing and everything is ok...

corrected cxmldocument (parts of it):

void cxmldocument::create(char* szstring)
{
m_size = strlen(szstring);
m_doc = new char[m_size+1];
memcpy(m_doc, szstring, m_size+1);
}

cxmldocument::~cxmldocument()
{
if(m_doc) {
delete[] m_doc;
m_doc = null;
}
}

and every viz-plugin using it needs a recompile...
