Problem with MatchCollection returned by the Regex.Matches

[Victoria Kagansky]

Hi!
Has anybody seen the following problem?
The Regex.Matches function returns a MatchCollection object containing all
successful matches of the expression in provided string. In several cases
the returned MatchCollection object seems to be corrupted. Access to its
Count property or attempt to iterate through it block the function, which
appears to keep running and to consume a lot of CPU.
Thanks,
Victoria
