Er, that was bash. Reverting to prelink-0.3.3-1 appears to fix the problem. This is very weird. The only changes in prelink were for prelink -uo, nothing else should be changed. Can you collect bash/whatever libs it uses and loads in a tarball when prelinked with 0.3.3-1 and with current prelink? Seems I lied about 0.3.3-1. I had been running 'prelink -u' and then just 'prelink /bin/bash' and it had been curing and reproducing the problem with 0.3.4. Then I installed prelink-0.3.3 and did the same, and bash still worked. But then I re-enabled the overnight cron job, and this morning everything was segfaulting again.

tarball
Could this be related to bug #147655 with new glibc? Yes, this is very likely the same thing. But only once a fix for #147655 is tested and the same fix cures this one I'd close this as a dup. |
