Hi Guys

I have a folder /usr1/bin/lts

its a company specific install, not a unix system folder.

lts was functional until i added some other programs to bin, all programs
run, lts can be executed only by root and not any user.

-rwxrwxrwx 1 jane bure 127158 2011-12-01 16:42 lts
[root@localhost bin]# ls -l ltf
-rwxrwxrwx 1 jane bure 205481 2010-05-18 06:37 ltf
ltf runs perfect for all users, lst only for root. segmentation fault for users. wat can it be?

ltf runs for both as well as all other programs. Wat can be wrong

Segmentation fault for users? Hm, file a bug.

General debugging steps:

(1) Run ldd to see what it links to. Make decisions/changes based on this info.
(2) Run strace to see what system calls it makes. Make changes/decisions based on this info.
(3) Run it with gdb. If debugging symbols are present, you might bet a great clue as to what's happening.

Yep, try ldd to scan for differences in the used libraries.

It could also be a sign of wrong error handling in programming: maybe some system call returns an error as only root can access certain files. But instead of testing the returned file pointer they just use it.

Recompiled the program and it worked.
Thanks.......
