Summary Simple JavaScript code leaks StructureIDs
Cameron Zwarich (cpst)
Reported 2008-10-10 15:36:06 PDT
The code for (var id in (new Array)) { } leaks 13 StructureIDs (in addition to the ones in JSGlobalData) the first time you load it, and then it leaks 2 more every time you load it. The code for (var id in (new Object)) { } leaks 11 StructureIDs the first time you load it, but does not leak any more when you load it again.

The leaks in the Array case are similar, and nothing seems Array-specific, so it is probably best to figure out the cause of the Object case first.
