That's really not pertinent. Post your main(), and any external routine
you might call to handle args, especially argv[0].

if it's 'myprog', after moving it to ~/bin or wherever, verify
that
'which myprog' returns ~/bin/myprog.
Seconded: check the $PATH. If that does not help, I suggest
eliminating
linked libraries as possible cause.
A quick checklist:
- Linked libraries: are they the same?
$ ldd ~/bin/myprog
$ ldd ~/src/myprog
- Are you using a debugging library like electric fence that may
cause
segfaults (on purpose)?
- Do you have any environment variables affecting the loader
(man ld.so)?
$ printenv | grep 'LD_'
- Are the C programs called from within a shell script that
calls the
C programs in a manner *different* than your test from the
command line?
- I suggest using strace to capture the segfault and see what
the
program (and its calling script?) were doing at that moment.
$ strace -o /tmp/mylog.txt -s 4096 -f ~/mypath/myprog
