I'm not sure what in the world's causing this crash. The stack trace
from gdb isn't much help.
Program received signal SIGSEGV, Segmentation fault.

Valgrind gives a little more info;

Here's the script that's being run when the crash happens:
d=i+v*0.2; r=t+i*PI*4; x=cos(r)*d; y=sin(r)*d
It crashes right before assigning x.
Here's where I compile and run the script:
int scope_load_runnable(SuperScopePrivate *priv, ScopeRunnable
runnable, char *buf)
{
printf("buf ------- %s %d\n", buf, (int)runnable);
HandleScope handle_scope;
Handle<Context> context = Context::New(NULL, priv->global);
Context::Scope context_scope(context);
Handle<String> source_obj = String::New(buf);
Persistent<Script> script =
Persistent<Script>::New(Script::Compile(source_obj));
priv->runnable[runnable] = script;
return 0;
}
int scope_run(SuperScopePrivate *priv, ScopeRunnable runnable)
{
printf("scope_run ---------- %d\n", (int)runnable);
HandleScope handle_scope;
Handle<Context> context = Context::New(NULL, priv->global);
Context::Scope context_scope(context);
priv->runnable[runnable]->Run();
return 0;
}
Here's the getter and setter:
#define GETTER(name) \
static Handle<Value> prop_getter_##name(Local<String> property,
const AccessorInfo &info) { \
Handle<Value> obj(*info.Data()); \
SuperScopePrivate *priv = (SuperScopePrivate
*)External::Unwrap(obj); \
printf("getter for %s = %f\n", *String::Value(property), priv-
>name); \
return Number::New(priv->name); \
}
#define SETTER(name) \
static void prop_setter_##name(Local<String> property,
Local<Value> val, const AccessorInfo &info) { \
Handle<Value> obj(*info.Data()); \
SuperScopePrivate *priv = (SuperScopePrivate
*)External::Unwrap(obj); \
priv->name = val->ToNumber()->Value(); \
printf("setter for %s = %f\n", *String::Value(property), priv-
>name);\
}
Here's cos:
static Handle<Value> function_cos(const Arguments &args)
{
printf("function_cos\n");
HandleScope handle_scope;
if (args.Length() != 1)
return v8::Undefined();
Handle<Value> val = Number::New(log(args[0]->NumberValue()));
return val;
}
And here's some output:
getter for i = 0.000000
getter for v = 0.199020
setter for d = 0.039804
getter for t = -0.050000
getter for i = 0.000000
getter PI
function_cos
getter for d = 0.039804
