In bug #506796 there is some discussion of prelink causing problems with libgcrypt. Is this the case? Should it be blacklisted?
The FIPS support in libgcrypt conflicts with prelinking. However the FIPS support is meant only for testing purposes in fedora - the module is not validated in the Fedora. So it does not make much sense to run it in the FIPS mode except for testing. It would not be a good idea to block prelinking just for testing purposes. Also if you'd like to run the whole system in the FIPS mode, you can disable prelink altogether on the distribution. As for the other issue that seems to be fixed by un-prelinking - I don't think this is a real conflict of libgcrypt with prelink - it rather seems that libgcrypt or prelink is somehow broken on the reporter's computer only. I am not aware of any other reports where prelinking libgcrypt made its users crashing.
Thank you.
