Description Pavel.A CLA 2011-05-02 21:02:36 EDT 
Parser does not understand and marks as syntax error expansion of macros like this:

#define dprintf(fmt, ...) printf(fmt, ## __VA_ARGS__)

dprintf( "foo %d\n", 123);  <<< marked as error
 
( Compiles OK with any decent gcc )

Comment 1 Markus Schorn CLA 2011-05-03 13:01:21 EDT 
I cannot reproduce the problem, the parser does understand these kind of macro expansions. If used outside of a function body the line is certainly a syntax error.

If you still think you have found a bug in CDT, then please provide 
* a code snippet that actually compiles 
* a description on how this is marked as an error (e.g. what does the hover   
  show when you move the mouse pointer over the error marker).
and reopen the bug.
