Omarchy

ProbeLabs65 findings · 95 requirements

A proof layer — requirements, tests and verified fixes — for two of Omarchy's subsystems: the application menu (launcher scripts, QML model, JSONC config, search and selection) and the lock screen (lock scripts, QML, PAM authentication). Scope is deliberately limited to those components of omacom/omarchy; the rest of the distribution is not covered.

Original report

omarchy-screensaver recursively handles SIGHUP until Bash segfaultsrevision 1 · captured 2026-09-28 21:24 UTC via poll

On Omarchy 4.0.0-1, omarchy-screensaver crashed with SIGSEGV while
dismissing/tearing down the screensaver.

The systemd-coredump command line was:

/bin/bash /usr/share/omarchy/bin/omarchy-screensaver

The symbolized core contains approximately 71,700 repeating frames through:

run_pending_traps
parse_and_execute
execute_command_internal

before crashing in array_rshift() at bash array.c:275.

GDB reports running_trap = 2, meaning Bash was executing the SIGHUP trap.
SIGHUP is configured to run exit_screensaver(). That handler kills the
org.omarchy.screensaver terminal while the same signal traps remain active.
Terminal teardown generates another SIGHUP, recursively re-entering
exit_screensaver before it reaches exit 0.

No OOM condition was present. This is the only recorded occurrence on this
machine.

The cleanup handler should disable/ignore its signal traps immediately upon
entry, or otherwise guard against re-entry, before killing the terminal.

System:
- Omarchy 4.0.0-1
- Bash 5.3.15-1
- ttfx 0.3.2-1

Related but distinct: #6762 covers ttfx aborting when its PTY disappears;
this report concerns the Bash supervisor recursively handling SIGHUP and
segfaulting.
