We've been successfully using cscope for a long time without major problems but recently, the size of our code base must have passed some threshold and the results of searches are no longer correct. Specifically, the number of matches, function names, line numbers and code snippets are all right but the file names are wrong, seeming to be almost random choices from within the code tree. The problem occurs in versions 15.5 and 15.6 on both Linux and AIX.
In case it helps, here are the sizes of some of the files, in bytes:
The filelist contains 68,576 files.
I'm hoping that this problem is not too hard to fix once the cause is found but finding the cause when I don't know the code is a bit of a challenge. Does anyone have any hints on which data structures or functions are likely culprits?
