# DP: bash-3.2 upstream patch bash32-039
BASH PATCH REPORT
=================
Bash-Release: 3.2
Patch-ID: bash32-039
Bug-Reported-by: rew@erebor.com
Bug-Reference-ID: <20070119065603.546D011E9C@kansas.erebor.com>
Bug-Reference-URL:
Bug-Description:
Bash-3.2 changed the behavior of the [[ command's `=~' operator when the
right-hand side was quoted: it matched the quoted portions as strings.
This patch introduces a new shell option: compat31. When enabled, it
restores the bash-3.1 behavior with respect to evaluating quoted arguments
to the =~ operator.
