This is happening because thread_stack is specified in my.cnf on affected distros:
root@wheezy:~# grep thread_stack /etc/mysql/my.cnf
thread_stack = 192K
root@jessie:~# grep thread_stack /etc/mysql/my.cnf
thread_stack = 192K
root@trusty:~# grep thread_stack /etc/mysql/my.cnf
thread_stack = 192K
Other distributions either don't have it specified to that value or not at all.
