Summary: misses some refernces to symbols.

Initial Comment:
LXR version 0.91 I think - downloaded it from
sourceforge about 2 weeks ago. There doesn't seem to be
any version info in any of the files. Latest entry in
CHANGELOG is '2002-02-03 11:29  mbox'

No error messages. Using mysql db. Indexing plain files.

The bug:
I have a C file with the line
    
ct += kill_task(ptask, sig, 0);  /* ANUPBS */

When I run genxref on the project containing this file
it fails to find the reference to kill_task. If you
look at the 'useage' table in mysql there's no entry
for that symbol in that file.

If I change the line to 

ct += kill_task(ptask, sig, 0);

and rerun genxref it seems to work just fine - genxref
finds the reference to kill_task, there's an entry in
useage, and an identifier search in the browser finds it.

A problem with the C comment parsing perhaps?
Cheers,
David Houlder dav...@an...

There are definitely some problems in the referencing code -
several people have reported missing references.

The problem seems to lie in the LXR::SimpleParse and
Generic::referencefile() code which is rather unclear and
depends on some fairly dodgy regexps.

If you wanted to spend some time stepping through this code
and isolating the bug it would be very useful.
