This would seem to be the case. The attached patch makes it work again. I doubt there's anything wrong with the actual code, only with the test assumptions of what makes a buffer 'large'. The system where this is reproducible has 16 GB RAM and 300 GB swap, which is quite a bit more than anywhere else where I tried this. I've now got strace output to compare, and I'll try to gain a better understanding of the problem before uploading a fixed package. > (credentials sent in a private mail) Thanks! I'm done for now, will ask again if I need another go. -- Niko Tyni nt...@debian.org
