Uninitialized member being used before set

• Component: JavaScriptCore
• Status: RESOLVED INVALID

[David Carson]

In kjs/property_map.cpp
In PropertyMap::mark()

  Entry *entries = _table->entries;

we are seeing a warning stating "Use of uninitialised value of size 4"

I'm thinking it's the entries array element 0 not being initialized in
the PropertyMapHashTable

struct PropertyMapHashTable
{
   int sizeMask;
   int size;
   int keyCount;
   int sentinelCount;
   int lastIndexUsed;
   PropertyMapHashTableEntry entries[1];
};

Though not 100% sure.

Do you have steps to reproduce?

This code no longer exists, at least not in a form anything like this. :-)
