// Notice we set the old gen heap size to 12 MB, which seems to be the minimum
|
|
// (in debug mode) to not cause us run OOM during isolate initialization. The
|
|
// problem here is that we pre-allocate certain exceptions, e.g. NullThrownError
|
|
// during isolate initialization, but if we have an allocation failure before
|
|
// that, we end up running into a recursive allocate/throw loop.
|
|
//
|
|
// Test that compaction does occur on repeated add/remove.
