Re: exit code -1073741819

Hi, Tom,

Thanks for the reply. I'll try to provide as much information as I can.

>The above is a fragment of a memory stats dump, which normally wouldonly be emitted if you had an out-of-memory situation. However thepart of it that you've shown doesn't indicate any particularly heavymemory usage. Were there any large numbers in the preceding similarly-formatted lines?

The lines that start with "ExecutorState" have similar big numbers and numbers in other lines are smaller.

>Was there anything possibly relevant in the logentries before that?

Logentries right after normal script output are listed below (those are just the ones on the top and the rest are similar):

Yes, it is Windows XP SP2. Sorry that I didn't mention it before.

>This is what is currently printed for an Access Violation trap on Windows. The fact that it came out partway through a stats dump is pretty suspicious; it suggests that the trap happened as a result of trying to scan the memory context bookkeeping data, which implies a memory clobber of some sort.So you're looking at a bug, but there's much too little data here toguess what the bug is. Can you get a debugger stack trace? Or put together a self-contained test case for someone else to poke at?

The spatial database that the script is using is quite large (about 4 GB). So I think making a self-contained test case would be the last resort. I'll reset some parameters and try to generat debug info. I'll post it here as soon as it is available.

>Actually the *first* thing to do is make sure you are up to date on both Postgres and PostGIS versions. No sense in spending a lot of timechasing down a bug if it's already been fixed.

The version of PostgreSQL is 8.2.4. PostGIS is 1.2.1 that is for PostgreSQL 8.2.4. So I think the installation is up to date.
