Usually there are no isolated patches for this kind of stuff. But
digging through the logs, this is likely what you want (no hard
guarantees though):

I've seen issues with TeX-live and mismatched shared libraries because
versioning some libraries wasn't handled correctly. This is why
TeX-live should be built with the libraries in its source tree
statically linked, unless you have the manpower available to sort out
any issues resulting form shared linkage.
