I find that I can not print local variables (none that is) if I use 4.4 for
compiling CP2K, while it goes fine with 4.3.

Reproducing requires these steps:

wget http://www.pci.uzh.ch/vandevondele/tmp/CP2K_2008_12_03.tgz
tar -xzvf CP2K_2008_12_03.tgz
cd CP2K_2008_12_03/
#
# change FCFLAGS to read
# FCFLAGS = -O0 -g
# be sure lapack/blas are available for linking 
# 
vi Makefile 
make
gdb ./cp2k.sopt
(gdb) run test.inp
^C
Program received signal SIGINT, Interrupt.
0x00000000006bb92a in __distribution_optimize_MOD_update_cost_cpu_diff () at
distribution_optimize.F:361
361            IF (local_cols_new(i).NE.local_cols_old(i)) THEN
(gdb) print i
No symbol "i" in current context.
(gdb) info locals
No locals.

wherever one breaks, local symbols can not be found. The same goes fine using
4.3.1
