BSON date field error on ARM CPU

[sptrakesh]

Hi,

I have been successfully using BSON as the primary model for a few iOS
applications (extracted from MongoDB 1.8.1 C++ sources). I am
currently working on a BSON structure that includes multiple date
types. Everything works fine on the simulator, but crashes on the
device with an unknown function error. The following screen captures
show the debugger window with (hopefully) enough information.

Thanks for any help in resolving this issue.

Maybe you can try my Obj-C codec instead: https://github.com/martinkou/bson-objc

There is also another project geared towards iOS dev (Objective C) here: http://github.com/martinkou/bson-objc 

I don't do iOS dev but I understand that it is mostly done in objective-c.

Also, the c-driver bson impl. might be something to look at as well since it is very light-weight and used in other drivers: http://github.com/mongodb/mongo-c-driver/tree/master/src In fact, I think the obj-c project just ported the version from the python source (which should be mostly the same).

Here is a date test:

Thanks for the replies. Since I am developing a cross-platform core
library, Objective-C is not an option. I will check out the c
library. That should be perfect for my needs.

The issue has been resolved, although I am not sure what the real
problem was. I found quite accidentally that I can safely use the
BSONElement.date() method without any issues on the device.
Attempting to use the Date() function still causes a crash, but since
date() things are good. Probably some Objective-C++ flakiness.
