I suppose it could equally well just have been a > mismatch between NSS 3.32.0 and NSPR 4.17.0? I realized that this is an ABI issue between nss-softokn-freebl and nss-util, not nspr. The upstream bug[1] introduced the aligned malloc functions which are only available in the newer nss-util package in Fedora[2] (not that nss-softokn-freebl dlopen's nspr and nss-util). I guess the fix would be to add either a versioned dependency on nss-util or stubs for those functions in nss-softokn-freebl. As this issue makes rpm non-functional, I would suggest people to ensure that nss-util is updated to 3.33 before updating nss-softokn-freebl, until it is fixed.
