Per the duplicate, crashes under createNotAnObjectError() also occur on Intel Macs.

Comment 9 2011-01-31 14:42:42 PST
Reproduced this crash with ToT plus the changes in r76925 (appropriately modified for other changes). Applying the changes in r76969 and the crash went away. The crash trace of the debug build shows the assertion failure of ASSERTION FAILED: m_runtimeObjects.get(object) This is what was fixed in r76969. With 76969, the assertion on line 189 is ASSERT(m_runtimeObjects.uncheckedGet(object)); *** This bug has been marked as a duplicate of bug 53271 ***
