Stacktrace on laptop wakeup

[fleaz]

Hey,

my swaylock just crashed after opening my laptop from sleep.

This is the stacktrace I got from gdb:

#0  0x00007f30317eed70 in xkb_state_layout_index_is_active () at /usr/lib/libxkbcommon.so.0

Some more details:

Dell XPS13 9300
Arch Linux
Swaylock 1.5-1
Sway 1.6.1-1

Let me know if I can help by providing more infos.

Best, Felix

The backtrace you provided doesn't contain debug symbols. This most likely happens because the Sway binary you're using doesn't have debug information bundled.

Can you try again with a manually compiled swaylock binary? Maybe also try ASan in case it's a memory corruption issue.

meson build/ -Db_sanitize=address

@emersion , I am seeing the following with swaylock compiled from https://github.com/swaywm/swaylock/commit/2bf76009e1d279a4194d37b9ee4f2bf0d9424d62 using -Db_sanitize=address:

./swaylock
==56919==LeakSanitizer has encountered a fatal error.

Attaching the resulting binary in case it can help with the investigation: swaylock.gz
