I tried to fix the offset problem. PFA the patch. It does solve the problem of setting wrong offset in ECPGdo() call.
But then there is problem of interpreting the result from server as an array within array of structure. The problem is there is in ecpg_get_data(). This function can not understand that the "field" is an array of integers (or for that matter array of anything) and store all the values in contiguous memory at the given address.

No, this looks like a bug to me. I haven't had time to look into the source codebut the offset definitely is off.
