For this reason I suspect the trace messages in this case will 
not help provide any addition information :(

only one function that is called in my application is:

 0806d080:trace:heap:HeapAlloc (40360000,00000002,00000018): returning
 4036168c Segmentation fault

and that fails :( 

That is why I suspect this is some sort of un-initialised global data 
in my application that is at fault.

I will give this a go.

Thanks for your help with this problem. Much appreciated.
