According to Debian Bug #559035 latest hardy kernel amd64 version is affected from same bug.

this can be reproduced by launching
$ for ((i = 0; i <= 100000; i++)); do exim4 -bV || break; done > /dev/null; echo "last: $i"

the machine isn't affected anymore by setting
$ sudo sysctl kernel/randomize_va_space=0

so the problem is process address space randomization. Here's the commit:

Please evaluate it, it's a serious bug.
