Are you using a CentOS or CentOS derived distribution and you experience deadlocks in dl_sysinfo_int80 function like this?:
#0 0x00ace7a2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2
#1 0x00cb248b in __read_nocancel () from /lib/tls/libpthread.so.0
#2 0x080bdf39 in el_push ()
#3 0x080bdfda in el_getc ()
#4 0x080bde50 in el_push ()
#5 0x080be11b in el_gets ()
#6 0x080a6f59 in main ()
Then you need to upgrade the kernel to the lastest version from the CentOS repositories (2.6.9-42.0.10.EL as of today):
yum upgrade kernel
Have Fun!
Yesterday, for a small project of mine, I needed to implement a small utility to deform jpeg images from command line. The idea was to use texture mapping for deformations, so I needed a way to manipulate the jpeg images at the pixel level.
The first thing I tried was the imagemagik utility. I’ve browsed their documentation but I couldn’t find anything close to what I needed. I wanted to be able to draw textured mapped triangles into a picture. I knew that the Allegro library that I’ve used back in the old DOS programming days could do the texturing part. The bad thing that I found out is that it does not know how to handle jpeg files 
Then I googled the Internet for a free and easy to use graphic library and I found libGD. The good thing is that it can handle jpeg files. The bad thing is that it cannot do the texturing part. The next thing I had in mind was to use both libraries but this would mean to add lots of dependencies to my small application for a simple texture mapping function. So I decided to write my own texture mapping function to remember the good old days. I will not describe how texture mapping works as there are plenty of tutorials on the internet for this.
