bash version: 4.3.27(1) and .bashrc / .bash_profile

Hi all!

I patched 4 servers some weeks ago ( bash version: 4.3.27(1) ) following the 
https://shellshocker.net/ guide (which it's a simple easy way for downloading 
https://ftp.gnu.org/gnu/bash/bash-4.3.tar.gz plus patches and compile it)

Today I realized some processes were not working as expected. After some 
investigation I've realized that when executing commands as:

su - [user] -c [command]

neither .bashrc o .bash_profile on user home directory are executed. If I just 

su - [user]

everything it's fine.

I've changed the user shell on /etc/passwd to the previous ( original 
vulnerable) bash and my scripts are back to work.

Servers are Fedora 6 (I know, a bit old... bus stable :-), CentOS and Oracle 
Linux. All of them RedHat based, just in case it matters. 

Should I take this as bug?. Or it's a side effect?. A fault in my side for some 
compilation option?

Thank you in advanced,
