Comment #9 on issue 362 by [email protected]: Nested brackets OOM crash in
regular expression
http://code.google.com/p/v8/issues/detail?id=362
This is actually unrelated. The crash comes from failing to create a very,
very large
flat string. When allocation fails, we create a Failure pointer encoding
the amount
requested, as well as some tag and type bits. This puts a limit on the
maximally
possible allocation request in 32-bit versions of 2^27-1. The maximal flat
string
length is ~2^28 (512MB space), and the maximal string length is 2^29-1, so
neither of
these limits catch the problem (we would throw an Out-Of-Memory exception
instead if
they did).
So definitly a problem, but unrelated to the RegExp one. I'll create a new
issue for
it.
