thanks for the report and the traces! I've seen exactly that backtrace in our
bugzilla:

https://bugzilla.redhat.com/show_bug.cgi?id=504257#c7

It was reported as a random error in a complex multi-threaded application. The
reporter hadn't had enough time to narrow it down to a minimal example. We
were not able to reproduce it, thus had to close it unresolved.

But you are saying it's "pretty reproducible". Could you please give us some
steps to reproduce it?

Are you using the original versions of libcurl and nss from Fedora? If yes,
please provide their NVR. Or have you compiled libcurl and/or nss on your own?

Thanks in advance for your answers!
