Hi group,

I had this problem before and though it was fixed with a new compiler.

• Compile C program in my laptop, FC8,
  gcc -v
  Using built-in specs.
  Target: i686-pc-linux-gnu
  Configured with: ./configure
  Thread model: posix
  gcc version 4.3.2 (GCC)
  
• runs fine on laptop.
• scp to my server, FC5
• runs fine under root
• Seg Faults for non-root ID

I used -static in the link.

Any ideas??

If you copied it to the server as "root," then the transferred files are owned by "root." The permissions of the files (and perhaps their location) might not permit anyone else to use them. This can apply both to the executable files or to any libraries.

Sometimes programs don't check whether an operation succeeded. They simply (say...) look-up the address of a routine they want to call, and attempt to call it using the address returned by the lookup function ... not checking if the address was NULL, as it would be if the routine could not be found. A subroutine-call to location $00000000 is a dead-certain superhighway to segfault-city.

I found that I can execute the program with an ID that belongs to the group root. So I am beginning to think it has to do with permissions?

From ls:

ls -lrt vmshub
-rwxr-xr-x 1 root root 698927 Mar 30 12:34 vmshub

But I don't see the problem!

The first thing the program does is output a message, so I don't think it is a program error.

Well, I found the problem. Don't know why this caused the problem, but I was trying to limit the size of data files for this user and I put a rule in ulimit_conf to limit the data file size to 5K. Removing this limit and the program now runs.

Can anyone explain what is going on??

Why should anyone explain you what's going on in your program ?

You have the source, so you can determine at what line the program segfaults.
