Comment #6 on issue 3878 by lidlanca: RangeError running RegExp on large
string
https://code.google.com/p/v8/issues/detail?id=3878
If the source string is not mutable on the regexp evaluation, I wonder if
that could be used for the backtracking implementation advantage.
Instead of pushing a copy of the source sub string to the backtracking
stack. A string wrapper will be pushed instead, the wrapper will represent
the source string range.
It should reduce memory footprint for cases where a backtracking is very
large and taking advantage of the string existence in memory
I am not aware of implementations details of regexp, so I don't know how
feasible it is.
