Hi,
It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated.
The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details:
The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=124995

It seems that we shouldn't assume that the object is of jsdisp_t type, reviewer may have already replaced it with any object type (it's probably fine to have a FIXME for that, through).

hres = E_FAIL; } jsstr_release(str);
- if(FAILED(hres))
- if(FAILED(hres)) {
jsval_release(ret);
This may be uninitialized if parsing failed.
You store hres in a local variable (which you could avoid, BTW), so you're not really saving anything. More importantly, if stack usage is a real concern, we should implement the algorithm without using recursion instead.
Well without that I'd have to add an output parameter, which seems pointless when the hres gets immediately propagated. I'll remove the local variable though, just in case it doesn't get optimized out. Apparently it makes it a bit less code, too.
