Using gdb to detect segmentation fault in sh?

I am using scientific linux. In the directory user/project/Build, after I ran 'make' to compile and link all the cpp files,I had no problems. But then, when I went to directory
Code:
user/run/run.sh

, which runs the project binary in
Code:
user/project/Build/bin/project

, I get a segmentation fault error. In the directory user/run, I enter 'gdb' in the command prompt and get the message
Code:
*** No targets specified and no makefile found.  Stop.

"

I then set the size limit of core files by

Code:
ulimit -c 75000

But when I enter

Code:
gdb /user/project/Build/bin/project core

I get

Code:
gdb /user/project/Build/core: No such file or directory.

When I enter
Code:
bt

, I get
Code:
No stack

When I then use the command prompt to go into directory

Code:
/user/project/Build/bin

and then type

Code:
gdb project

and then "run", I get

Code:
Thread debugging using libthread_db enabled.. Program exited with code 01.Missing separate debuginfos, 
use: debuginfo-install glibc-2.12-1.149.el6_6.4.x86_64 libICE-1.0.6-1.el6.x86_64 .

..

What am I supposed to do to detect the segmentation fault?
