users cant execute program in bin but root can

[ndaka123488]

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

Might be lts file depends on some other file which only root can execute . set-uid may works in this case.
