Crash in debugger beneath MarkStack::drain @ me.com, ibm.com
https://bugs.webkit.org/show_bug.cgi?id=57080
<rdar://problem/8525907>
The crash was caused by changes in the executable after recompilation.
The fix is for the activation to copy the data it needs instead of
relying on the data in the executable.
SunSpider and v8 report no change.
* runtime/Arguments.h:
(JSC::JSActivation::copyRegisters): Use our own data members instead of
reading data out of the executable.
* runtime/JSActivation.cpp:
(JSC::JSActivation::JSActivation): Initialize our data members.
(JSC::JSActivation::markChildren):
(JSC::JSActivation::symbolTableGet):
(JSC::JSActivation::symbolTablePut):
(JSC::JSActivation::getOwnPropertyNames):
(JSC::JSActivation::symbolTablePutWithAttributes):
(JSC::JSActivation::isDynamicScope):
(JSC::JSActivation::argumentsGetter): Use our own data members instead of
reading data out of the executable.
* runtime/JSActivation.h: Added new data members to track data previously
tracked by the executable. Since I've removed the executable pointer,
on a 64bit system, I've only made activations bigger by an int.
