Does the version from 7.1 work better? No, my friend tested it on 7.1, it crashed Can you tar up the directory structure (no files) and post it? Never mind, I seem to have reproduced something similar. Adding jakub to cc: list, this may be a glibc problem. Seems all fixed and happy by 8.0 |
From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.2.19 i586; Nav) Description of problem: When I've got a huge amount of subdirectories and run slocate to create a slocate database, slocate gets a segfault. I'm talking about _ALOT_ of subdirectories. How reproducible: Always Steps to Reproduce: 1. Create a huge amount of subdirectories (asdf/asdf/asdf/asdf/asdf style), just use cp dir dir -Rf or something 2. Run slocate/updatedb to create an slocate database, like it's run by default by cron (/usr/bin/updatedb -f "nfs,smbfs,ncpfs,proc,devpts" -e "/tmp,/var/tmp,/usr/tmp,/afs,/net" as root ofcourse, you might want to add -v to see what files slocate is processing) Actual Results: after i ran updatedb i got: /usr/bin/updatedb -f "nfs,smbfs,ncpfs,proc,devpts" -e "/tmp,/var/tmp,/usr/tmp,/afs,/net" warning: updatedb: could not open database: /var/lib/slocate/slocate.db: No such file or directory Segmentation fault Expected Results: Well, first of all, it shouldn't segfault, normally it just completes and creates a database, then exit's with out a message. Additional info: Here's what i got when i ran the program through gdb: [root@tannbursti /]# gdb /usr/bin/updatedb GNU gdb 5.0 Copyright 2000 Free Software Foundation, Inc.

This is the first bug i submit, sorry for my english, it's not my native language.
