LAMarker is a tool to set/unset Large Address Aware bits, in the PE header of a binary. It can be used for instance to make the XE3 and upwards C++ linkers Large Address Aware, and allow you use the -GH command line open to adjust the linker heaps.
USAGE: LAMarker [options] -FFileName

Options :
-Q Quiet
-? Help
-M Mark as Large Address Aware
-U Unmark as Large Address Aware

If no options are specified other than -Ffilename.exe then the PE header flags and checksum will be displayed.
If you specified the -M or -U the original file will be backed up with the extension .old

Using the LA marked linker you might see this issue more often (although you do see this occasionally in the normal linker):

1) You have an application that just works...
2) You move a control in the dfm, no code changes.
3) MAKE... the application crashes in the start up code, in a number of cases it will be in the delayloading code.
4) When you make some code change OR a clean and a build, the application will work again.

To resolve this issue, you set the linker options to clear the state files before a link,
(in the IDE Project | Options | "C++ Linker" | Advanced | Clear state before linking ->TRUE, it is the "-C" option
for the command line linker) this is counter productive for incremental linking, BUT you will not get this mysterious
startup crash.
