title: Segmentation fault after installing the glibc 2.7
body: <p>I tried to update my glibc library to 2.7 version. My compile  process are showing here:  </p>
  
  <pre><code> ../configure --disable-debug --disable-dependency-tracking CFLAGS=\
   "-U_FORTIFY_SOURCE -O2 -fno-stack-protector" --disable-silent-rules\
   --prefix=/disk2/hyf/lib/glib-2.7 
  
   make &amp; make install  
  </code></pre>
  
  <p>Due to the limitation of privilege， I had to install it in non-default search directory(e.g <code>/usr/local/lib</code>). </p>
  
  <p>After I added <code>/disk2/hyf/lib/glib-2.7/lib</code> to <code>LD_LIBRARY_PATH</code>, the problem happened. </p>
  
  <p>Typing <code>ls, ll, vim</code> etc normal command, it all come with error <code>Segmentation fault</code>.</p>
  
  <p>I have searched the Internet, and found two reasons may related to the <code>Segmentation fault</code>issue. (1) The  glibc-2.7/lib is not compatible with gcc/lib of the system(The gcc version with the centos system is gcc 3.4 and I have also installed gcc-4.9 successfully as the replacement) </p>
  
  <p>(2) The glibc-2.7 was installed at non-default path. </p>
  
  <p>I have no clue to fix my problem due to any commands can't work well. How to fix this problem?</p>
  
  <p>What's more, does my error effect other user(I'm a non-sudo user of the Linux cluster)?</p>
