9 years ago Here's another, much longer valgrind trace, with leak-check=full and track-origins=yes -- it's worth nothing that the valgrind output is the same, regardless of whether I see segfaults logged or not:
I'll try to get this resolved, but I've simply disabled caching for the time being. Thanks!

9 years ago Could you run openufp in debug mode and submit the logs? I think it's the hash which is causing troubles.

9 years ago Sorry for the delay, Jeroen. Here's debug output with the caching set to the default:
I hope to get some time to get this fixed some time this weekend! Thanks for the help, and a great project.

Sorry, I feel like we're pushing this app to new limits ;-)
We're getting segfault errors when using caching -- doesn't appear right way, but after running for a while we do see it:
