However that 'legacy code' will probably apparently work right for quite a while, even if you correct nothing. It should do a good part of the job, at least if you haven't defined function where an argument of type int is actually a memory length.

It also includes all the code that uses 'int' to store the difference between two pointer, or the length of a memory area, instead of using the correct type 'size_t' : 'int' being signed has 31 bits, and can not handle a value of more than 2 Gb.ДЄ way to cure a good part of your code is to go over it and correct all of those innocuous 'mixing signed and unsigned' warnings.

No, 'legacy code' in this context (C/C++) is not exclusively code that plays ugly tricks with the MSB of pointers.

As a programmer, what do I need to worry about when moving to 64-bit windows?.

See: Unit Testing for x86 LargeAddressAware compatibilityДЄlso very 'related' and quite interesting is the migration from 32bit code to 64bit. The MemTopDown registry switch is not achieving the desired results for unit tests that are executed by a 'test runner' that itself is not LAA enabled. unless this is done you better remove the LargeAddressAware flag from your executable. When encountering issues with 3rd-party modules you need to ask the author to fix his bugs. Just to name one very obvious example: use unsigned integers instead of signed integers for memory pointers. When applying the LAA flag to your 32bit executable it is mandatory to fully test it on a ењ†4 OS with the TopDown AllocationPreference switch set.ДЇor issues in your own code you may be able to fix them. Side note: for first analysis i strongly recommend the tool VMmap ( SysInternals). Ideally you'll see them 'right from the beginning'. With this switch enabled you will identify issues 'sooner' rather than 'later'. This forces all memory allocations to go from the top down, instead of the normal bottom up.

Luckily there is an extremely handy system-wide switch built into the windows OS:ДЇor testing purposes use the MEM_TOP_DOWN registry setting. they will sporadically show up 'sooner or later'. If such bugs exist they are hard to identify. this is hiding bugs related to high addresses. so, unless your process consumes a lot of memory (or it has a very fragmented virtual address space), it will never use addresses beyond the 2 GB boundary. Usually, memory allocation returns virtual addresses in low-to-high order.

So don't restrict the VAS for the process to 2 GB but unlock the full range (of 4 GB)'.Дo you take responsibility for all the system DLLs, microsoft redistributables and 3rd-party modules your process may use? Yes, my application (and all DLLs being loaded during runtime) can cope with memory addresses up to 4 GB. Blindly applying the LargeAddressAware flag to your 32bit executable deploys a ticking time bomb!Д«y setting this flag you are testifying to the OS:
