Exception from HRESULT: 0x800F1001 after clients install Windows Update KB 3000850

Question

We're having a problem with our windows store app that is making our app unusable.  We're getting an unhandled xaml exception during start up with the underlying com exception hresult 0x800F1001.  We've verified that this only happens to users who have installed the optional windows update KB 3000850.  Is anyone else having a similar issue after the update?  Anyone know what the message attached to that HRESULT is?

Hi Kellen,

Can you reproduce this issue on your development machine? I would recommend you reproduce it first and then try to find what code is the root cause. If this caused by user code, please try to post more information about it here. If this caused by runtime system, please open a thread on http://connect.microsoft.com/.

Please feel free to let me know if you have any concerns.

Regards,

Looks like it may be a heap corruption issue in our native component.  The heap corruption seems to be exposed after this update.  I'm trying to debug it a bit further, but I think it's fair to say the bug is actually on our side.  Thanks for the reply though Herro.
