I committed VB-Regex-lr.34 to the PharoInbox that fixes this issue.
In fact, this is a completely new port of VB-Regex with numerous
bug-fixes and enhancements. The bug you found was fixed in version
1.1c in December 2004. The version 1.1 we used up to now was from
October 1999.
The detailed log of changes from Vassily you can see below.
Cheers,
Lukas

Ancestors: VB-Regex-StephaneDucasse.33
VERSION 1.2.3 (November 2007)

Regexs with ^ or $ applied to copy empty strings caused infinite

loops, e.g. ('' copyWithRegex: '^.*$' matchesReplacedWith: 'foo').
Applied a similar correction to that from version 1.1c, to
#copyStream:to:(replacingMatchesWith:|translatingMatchesUsing:).
2. Extended RxParser testing to run each test for
#copy:translatingMatchesUsing: as well as #search:.
3. Corrected #testSuite test that a dot does not match a null, which
was passing by luck with Smalltalk code in a literal array.
4. Added test to end of test suite for fix 1 above.
VERSION 1.2.2 (November 2006)
There was no way to specify a backslash in a character set. Now [\]
is accepted.
VERSION 1.2.1	(August 2006)

Support for returning all ranges (startIndex to: stopIndex)

matching a regex - #allRangesOfRegexMatches:, #matchingRangesIn:
2. Added hint to usage documentation on how to get more information
about matches when enumerating
3. Syntax description of dot corrected: matches anything but NUL  
since 1.1a
VERSION 1.2	(May 2006)
Fixed case-insensitive search for character sets.
VERSION 1.1c	(December 2004)
Fixed the issue with #matchesOnStream:do: which caused infinite loops
for matches
that matched empty strings.
VERSION 1.1b	(November 2001)
Changes valueNowOrOnUnwindDo: to ensure:, plus incorporates some  
earlier fixes.
VERSION 1.1a	(May 2001)

Support for keeping track of multiple subexpressions.
Dot (.) matches anything but NUL character, as it should per

POSIX spec.
3. Some bug fixes.
2009/11/4 Stéphane Ducasse stephane.ducasse@inria.fr:
...
...
l := '1ère partie\nmilieu\nfin'.
'.*' asRegex matchesIn l.
-> infinite and freezing loop.
