Subject: Anchored Regexp get stalled or hung

Dear rubyists!

I dare to post this question in spite of fact that lately there were
many posts about false RE bug reports.

I've tried to make following regexp

     a=/^-{150}/

and it turns out that such expression hangs ruby interpreter.
I've checked that re{m,n} expression allows by design as much as
32766 repetitions. Expression such as

     /-{32766}/

works fine, and

     /-{32767}/

produces error message:

     'too big quantifier in {,}: /-{32767})/'

But when regexp is anchored at front you can not specify more
than 127 repetitions:

     /^-{127}/

is ok, but

     /^-{128}/

hangs interpreter. Is it a bug or not?
