iPhone crash

[GoogleCodeExporter]

Please delete (ignore) issue 64.  Not sure why I cannot reply to it (using 
Firefox, page is throwing errors on PC and Mac).

Released app crashes.  Cannot reproduce this error in development environment.  
Reported by Apple, and also by a user in an app that made it into the store.

Error occurs at app launch/initialization.

New info from my programmer:  he had been "precompiling" this library and 
including it.  When he "fresh compiled" the source code from this library for 
each individual app, the problem went away.  It is slower, but we think it will 
works.

This does not address whatever the real problem is, but hopefully it will keep 
someone from pulling an all-nighter to get apps released.

Thanks for the new information.

It sounds like an inconsistent set of build settings between the library and 
the apps.

I had one user with the same issue.  I am changing build settings now and 
resubmitting to Apple.  I will post back when I find out if it works for the 
user.

I found a solution in my case.
Open GData.xcodeproj file.
then set "Info >> Build >> Architectures >> Standard (armv6 armv7)" 
and rebuild your project.

This does seem to solve the problem. My programmer figured out the release 
build and the dev build are (or at least were) different for this project.  
Thus unless it is changed by the user, they are likely to encounter the same 
issue:  testing/development will be fine, but the released app will fail.

Worked for me as well.  I just matched BaseSDK and deployment target settings 
for all projects involved and it seems to work so far.
