New issue 3791 by [email protected]: Weak callback not called for all
objects returned from generators.
https://code.google.com/p/v8/issues/detail?id=3791
I'm attaching a modified version of d8.h and d8.cc to demonstrate a problem
I'm seeing with v8 3.24.
Replace d8.h and d8.cc with the attached.
[v8-3.24]$ make -j8 x64.debug werror=no library=shared
[v8-3.24]$ cd out/x64.debug
[x64.debug]$ ./d8 --harmony-generators --harmony-iteration
d8> function* gen(lim) { for (var i = 0; i < lim; i++) yield wrap(new
Date())};
d8> var i = 0;
d8> for (var t of gen(2)) {i++;}
Shell::Wrap adding 0x1862400
Shell::Wrap adding 0x18713d0
1
d8> notify();
WeakCallback clearing 0x1862400
d8> notify();
d8>
What I see is that the 2nd wrapped object at 0x18713d0 never receives a
callback even after garbage collection is invoked.
