Re: Freeing sqlda from DESCRIBE INTO statement

I've been running into the same problem on NT/VC++6.0sp2 using the same configuration below and when I call my debug version of free (Microsoft's _free_dbg) it complains that the pointer that I'm freeing (the sqlda) hasn't been allocated from within my own heap. I can only find one example Informix esql program that uses free on the sqlda (demo3.ec). All the other examples don't appear to be free'ing the sqlda directly. We have code on UNIX that uses free and behaves correctly on all platforms that we support, but the WinNT debug heap seems to be a major hang up. Does anyone know how to deallocate this resource on exit on NT?
