[cfe-dev] [Debug Info] Wrong column numbers come from macros

[Alex Denisov via cfe-dev]

Hi,

I see an issue with debug info and macro. Here is an example:

#define f(x) x
...
int a = f(b + c);
        ^

The debug information for each node in 'b + c' points to the 'f' (see the caret). I expect it to point to the actual source location.

I assume that is a known issue, but I could find neither explanation nor bug report.
Can somebody shed some light on the issue?

Cheers,
Alex.
