// Bug 689101 - if the binary layout of jsval does not match between C and C++
|
|
// code, then calls to functions returning jsval may get compiled differently
|
|
// than the callee, resulting in parameters being shifted over by one.
|
|
//
|
|
// An example is where on Windows, calling jsdValue.getWrappedValue() will
|
|
// return a random floating point number instead of an object.
|
|
//
|
|
// This test must be run with debugging already enabled
