Thanks for your quick reply. I rebuilt the kernel but it did not work. 
However, recompiling without -O2 did it for me.

What I did (for those who might run into the same problem):

#cd LVM/1.0.1rc4
#./configure
 >>> here, edit make.tmpl to change CFLAGS=.... -O2 .... to CFLAGS=... 
-O0 ... <<<
#make
#make install

Thanks again for your time and quick answer.
