Bug #11038: regular expression fail

ruby -v:
ruby 2.0.0p598 (2014-11-13 revision 48408) [x86_64-linux]
Backport:
2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
[ruby-core:<unknown>]

Description

the following regexp seems to loop
/^([A-Z0-9_%+-]+\.?)+[^.]@([A-Z0-9-]+\.)+[A-Z]{2,4}$/i

with "ec-mat-charles-perrault-voves-28@ac-orleans-tours"

you can test with:

'ec-mat-charles-perrault-voves-28@ac-orleans-tours' =~ /^([A-Z0-9_%+-]+\.?)+[^.]@([A-Z0-9-]+\.)+[A-Z]{2,4}$/i

Seems a backtrack explosion.

Is the ? just after \. really intentional?
