ยฏ_(ใƒ„)_/ยฏ either systemd managed that or it's in your current dir, but forget it, the error is in src/sessions.c:55 (mfw I forget \n). Can you tree /usr/share/xsessions and /usr/share/wayland-sessions ? Permissions too? Or if you can just send those to me I can replicate the issue in a sec.

strace ./lidm 2> /tmp/lidm.log will run lidm but list syscalls into /tmp/lidm.log (what strace does)

grep open /tmp/lidm.log will grab the lines that have open in it (opened files), I just wanna knoe which wae the last file opened, I think it's a logic error freeing after parsing that session file

grep open /tmp/lidm.log

gotcha, a lot of lines

doesn't make sense, opening files is sequential, last opened file fails to open, which just returns the function and the only thing it does after is 1 realloc and 2 variable assignations, no double free unless the last file to open didn't fail to (which isn't the case, but it'd be a logic error parsing the file, I'm looking at it and I can't see any possible double free)
