Bash Version: 4.1
Patch Level: 2
Release Status: release

Description:

     The [[ str =~ "^pattern" ]] operator no longer works correctly.  "^"
     is treated as a literal instead of matching the beginning of the line.

Repeat-By:

     [[ "-h" =~ '^-h' ]] ; echo $?
     Should return 0, but instead returns 1.

It was bug in previous versions of bash in fedora and RHEL.
This behavior is correct now.
