I'm currently running FPC 2.4.4 (built from SVN) on Windows Server
2008 R2 cross-compiling targeting Win64/x86_64. I retrieved lazarus
0.9.30.2_rc2 from subversion and built the LCL to be able to target
win64/x86_64 for GUI apps as well. I then follow these steps:
1. Create a new application
2. Add a TMainMenu to the form
3. Add a single menu item to the main menu
I compile the application for win64/x86_64 and run it. Upon running
the app, I get this:
Range check error.
Press OK to ignore and risk data corruption.
Press Cancel to kill the program.
The backtrace shows:
C:\temp> .\project1.exe
TApplication.HandleException Range check error
Stack trace:

I tried googling for a similar issue but didn't see anything specific
to TMainMenu with win64. I'm sort of baffled by this, since I can't be
the only one out there trying to target win64.
Has anyone else seen this?
