Just wanted to let you all know that I finally solved this. I was able to figure out that it only happened when storing into a memo field in the error log and only after the application’s reindex utility indexed the errorlog table. I instead recreated the table, and added the indexes manually, and all is well.

I suspect it means my client and I need to spend some time understanding what was different about my manual indexing than what the code does, but in the meantime, I’m not able to get errors without crashing out of VFP.

Thanks to everyone who offered suggestions.
