dumpbin output

When I run dumpbin to list the exported functions from a DLL I get this output:-

At least, that's the output I get when I run dumpbin in Windows 7. But if I run the same version of dumpbin in Windows XP (on exactly the same DLL) I mysteriously get some extra information:-

I've never noticed that extra info before (the sections beginning = @ILT+). Is it anything to be worried about??

I found this reference suggesting that it has to do with intermediate linking.

The XP vs 7 difference is interesting.

Thanks Codeplug, you're right. Now that I checked a bit deeper I noticed that I only see this with my Debug DLLs. Traditionally, I've always built my Debug builds with incremental linking turned on and my Release builds with it turned off.

I'm not sure if there's a pattern here - but I only tend to see it if I check the file on the same system it was created on. So if the file was created on Win7 and I run dumpbin from WinXP, I don't see the extra info (and vice versa).

Strange.... :confused:

Perhaps the difference is that dumpbin has access to the PDB on your dev machine - as this seems to suggest: http://msdn.microsoft.com/en-us/libr...f(VS.100).aspx
