New host: CentOS 7 Running directly on the host, with repositories over sshfs as before:
[email protected]:fossils on /fossils type fuse.sshfs (rw,nosuid,nodev,relatime,user_id=0,group_id=0) I'm not a C dev, so I'm largely unfamiliar with this type of debugging; let me know if I need to handle this differently somehow. For better readability, I've also posted the debug output here: https://paste.pound-python.org/show/QWBnPqc953rXnFK4pxOg/ ``` [root@localhost fossil-2.4]# gdb ./fossil [45/2179] GNU gdb (GDB) Red Hat Enterprise Linux 7.6.1-100.el7 Copyright (C) 2013 Free Software Foundation, Inc.
