SQLite 64-bit library crashes when sqlite3_prepare_v2 fails

I'm compiling both a 32-bit and 64-bit SQLite library with Microsoft Visual C++ from the command line for a simple C#开发者_开发百科 wrapper. The 32-bit version works fine, but the 64-bit version crashes my application completely when sqlite3_prepare_v2 returns anything but SQLITE_OK.

build.bat

set ARGS=/nologo /LD /DSQLITE_ENABLE_COLUMN_METADATA sqlite3.c /link /def:sqlite3.def

call vcvars32.bat
cl %ARGS% /out:sqlite3.dll

call vcvars64.bat
cl %ARGS% /out:sqlite3_64.dll

C# code (relevant bits)

public delegate int _sqlite3_prepare_v2(IntPtr db, string zSql, int nByte, out IntPtr ppStmt, out IntPtr pzTail);

public static readonly _sqlite3_prepare_v2 sqlite3_prepare_v2;

IntPtr tail;
if (SQLite.sqlite3_prepare_v2(_db.Handle, text, -1, out _handle, out tail) != SQLite.SQLITE_OK)
    throw new SQLiteException(_db);

The functions are bound at runtime so that I can compile for Any CPU and choose which version of the library to use. When I run this on a 64-bit system, I get this:

Any ideas?

EDIT: The message I get when debugging the application is:

A heap has been corrupted

SQLITE_MISUSE implies that you're using the library in a bad way. If you can change your code to not trigger that in 32-bit, I suspect that your 64-bit crash will go away.
