Here is some more information and related bugs on the issue: https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/22410.
Essentially, readlink() on /proc/self/exe will return the path of the executable that calls it, but on an unionfs based system, it will return the wrong path (/squashfs/usr/bin/mono). THe old patch simply commented out the check on /proc/self/exe, which obviously was a bad idea, and also causes random segfaults all over the place (currently evolution- sharp is known to FTBFS due to this issue, f-spot also FTBFS if its rebuilt after clearing its dependency issues). THe replacement patch (which I'm now testing) checks the prefix of any path read via the readlink /proc/self/exe function call, and then strips off the bad section of the path as necessary. As evolution-sharp is known to trigger this bug, my test will involve building it once in a normal chroot jail, and building it again on the liveCD with the replacement mono. It should success both times if mono has properly been fixed. ** Summary changed: - Ubuntu mono patch dont_check_proc_self_exe causes FBFTS in evolution sharp + Ubuntu mono patch dont_check_proc_self_exe causes random segfaults in mono -- Ubuntu mono patch dont_check_proc_self_exe causes random segfaults in mono https://bugs.launchpad.net/bugs/247782 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
