RE: Invalid heap space using HTTPAPI
Thanks for finally sending some almost useful information!
Make only one change a time and test so we know what eventually cures the patient.
You are running an old version. You really should be able to run this (especially in a test environment) with the latest version. As has been pointed out, backwards compatibility is very good. At least run a test WS.CONTACT with the new version so that we know it is a current problem. Download the Beta and install into a different library. Compile and run using the new version.
>From limited experience, changing ptr between alloc and dealloc will cause a problem. If that happens, why?
Did you dump the program? Program dump listing? Not sure it would help, but can't hurt when debugging. What is the value of "ptr"?
Is there a pointer declared in your module WS.CONTACT called "ptr"? Are you using it? I don't think it needs to be there. If not, please delete and retry test.
Add some debugging output...print the ptr value at the point where it allocates memory. Print it just before the dealloc. The pointer should be the same. Here is an article that talks about one way to print a pointer http://www.itjungle.com/fhg/fhg110310-story02.html. HTTPAPI is full of pointers and uses arrays of pointers in some places.
If you run this for the record at 176,677, do you get the error?
If you read the first 1000 records without calling getContactInfo, then let it run, do you get the error at 177,677? In other words, does it always crash after running 176,677 iterations regardless of the data you reading? Or at least within a few records of that?
If you watch the program running, do you notice anything unusual? Stack growing? Files growing?
Good of you to send a compile listing for the code so we can see the file layouts and other copied information...if want us to try to recreate, we also need just the source without the other stuff and maybe just a bit of knowledge on how to fake it. But try the new version, try the ptr removal, try printing the ptr. Let's see how far we get.
