Looks like a path that you might find in a checked (== with assertions) build of Windows 7 as a source path in the output of failed assertions. However, it could be a fake to make something appear more legit. You're tagging the question as malware but I don't quite see the connection.
Given the path it would not be inconceivable to think that this is some code that uses an older version of
ntdll.dll loaded by another name. Stranger things have happened, such as loading a second
ntoskrnl.exe to dodge a possibly patched running kernel.
Anyway the RTM in
w7rtm means release to manufacturer and refers to the very first release version of a Windows. And given that this refers to Windows 7, this is several years old by now.
