[V8] Error objects keep hard-reference to the functions on the stack |
||||||||||||
Issue descriptionVersion: 52.0.2738.0 (Official Build) canary (64-bit) - V8 5.2.323 OS: OSX 10.11.4 (15E65) What steps will reproduce the problem? (1) Open the attached HTML file (2) Open the "Developer Tools" (3) Go to the "Profiles" tab (4) Select the "Take Heap Snapshot" and take a heap snapshot (5) Select "Snapshot 1" in the list of snapshots (6) Open "(string)" in the tree (7) Click the string object starting with "BigString..." of about 90MB (8) The "Retainers" panel shows that "myError" is the only object keeping this object alive What is the expected output? The BigString should be garbage collected. There is no way to get a reference to the string using JavaScript code. What do you see instead? The string is not garbage collected.

This is the combination of two things: - bigStrig gets context-allocated. - the stack trace keeps the functions on the stack alive. |
