gcc 4.4.6-4 contains many bugs, which already fixed in 4.4.7-11

and these gcc bugs can originate bugs in OpenVZ kernel,
compiled with this very old and buggy gcc version.

more specific:

https://gcc.gnu.org/bugzilla/buglist.cgi?bug_status=RESOLVED&resolution=FIXED&target_milestone=4.4.7

- list of problem reports (PRs) from GCC's bug tracking system that are 
known to be fixed in the 4.4.7 release. This list might not be complete 
(that is, it is possible that some PRs that have been fixed are not 
listed here)

also see output of # rpm -q --changelog gcc | less
to see Red Hat backports and fixes over gcc version 4.4.7
