v6.x: backport V8 fixes for parser bugs by targos · Pull Request #12037 · nodejs/node

Original commit message:

    Properly handle holes following spreads in array literals

    Before this change, the spread desugaring would naively call
    `%AppendElement($R, the_hole)` and in some cases $R would have
    a non-holey elements kind, putting the array into the bad state
    of exposing holes to author code.

    This patch avoids calling %AppendElement with a hole, instead
    simply incrementing $R.length when it sees a hole in the literal
    (this is safe because $R is known to be an Array). The existing
    logic for elements transitions takes care of giving the array a
    holey ElementsKind.

on the 6.10.x release line.

This includes:

 * a fix for memory leak in the crypto module that
   was introduced in 6.10.1
 * a fix for a regression introduced to the windows repl in 6.10.0
 * a backported fix for V8 to stop a segfault that could occur
   when using spread syntax

It also includes an upgrade to zlib 1.2.11 to fix a numberof low
severity CVEs that were present in zlib 1.2.8.
