I just ran into the same issue. It seems like Aglasterr() is implemented using a file on disk (global!) which is never cleaned up. There is an agreseterrors() in the C code, but it's never called... and doesn't look like it removes the file anyway.

This has been driving me insane all week. I thought it was certainly a Vercel issue because I wasn't experiencing it locally, but rather only when I deployed it to Vercel's edge network, but I guess the strange behavior is actually that I wasn't experiencing it locally.

Did anyone find a workaround? If not, I'm willing to try to make a PR with the fix, but I'm not super familiar with Go or C.

I made a PR that fixed my use case. Hopefully a maintainer can take a look at it and accept it soon. But if not, I'm hosting my own version of the package with the fix here.

This issue has been fixed with the merge of 865af03, and can be closed now.
