In last version I used (0.9.10) it worked fine. Now I jumped to 1.2.0 and noticed couple of things and cannot understand whether it is a bug or just I misconfigured LXR:
1) While viewing directory list all files have 'Not valid' in 'Last indexed' column.
2) When viewing file I have on top message in red : "Warning, cross-references for /DIR1/DIR2/FILE_NAME.c need to be fixed."
3) When I click on some link in the text of file in previous version it showed on top first small table with prototypes and definitions and lower it showed table with all places in files where it is used. Now it shows only first top table. To get second table I need to put function/variable name in 'General search' -> 'Or containing' and then I have it. And honestly from my point of view it was MOST USEFUL feature of LXR. And now I need to do it manually all time.
