Linking with the LLVM C++ Standard Library corrupts any value stored in the database. #54

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
=========================

Compiling an application with the LLVM C++ Standard Library 
(http://libcxx.llvm.org/) with Xcode corrupts any values written to the 
database file.  The keys are uncorrupted.  The values appear to be fine until 
the database is closed and reopened.  Using the GNU C++ Standard Library works 
fine.

What is the expected output?

Seems to be working with both standard libraries now.  I'm not sure what 
happened.  I'll update if I have more information.

As always, re-open or file a new bug if you see this again.
