Summary: xdebug.trace_output_name = "xdebug.%c" does not function as documented.
Description:
If i set the above option trace file names will be build like this:
"trace.PID.xt".
According to http://xdebug.org/docs/all_settings it should be
like this trace.CRC32.xt.

That's not what the code says, the code is doing what the docs say:

case 'c': /* crc32 of the current working directory */
    VCWD_GETCWD(cwd, 127);
    xdebug_str_add(&fname, xdebug_sprintf("%lu", xdebug_crc32(cwd,
strlen(cwd))), 1);
    break;

case 'p': /* pid */
    xdebug_str_add(&fname, xdebug_sprintf("%ld", getpid()), 1);
    break;

How do you see that the results are wrong?

Thats strange. I have the following configuration option in the php.ini:
xdebug.trace_output_name = xdebug.%c and no overriding directives in any
included apache config.

I restarted the apache and tried again:

 # ls -l trace*
                                                   
 -rw-r--r-- 1 www-data www-data 94689 2007-05-30 00:22 trace.11061.xt
 -rw-r--r-- 1 www-data www-data 7940 2007-05-30 00:23 trace.11116.xt
 -rw-r--r-- 1 www-data www-data 352669 2007-05-30 00:25 trace.12604.xt

Thats the output.

I'm using the current cvs version and found the lines you quoted in
usefulstuff.c, so i guess the error before. Maybe while parsing the
configuration?

If i set "xdebug.trace_output_name = xdebug.%t" the same happens. The PID
is used not the timestamp (->trace.12767.xt).

Strange, could you please check whether the settings that you make actually
reflect in the output of phpinfo()? Although that wouldn't make sense as
the default is crc32 as well. Could you also try the following:

xdebug.trace_output_name=xdebug.%c.%p

To add both options?

Derick

Sorry, i didn't noticed your request. phpinfo() confirmed my
configuration.
I tried both
  xdebug.trace_output_name=xdebug.%c
  xdebug.trace_output_name=xdebug.%c.%p
and now both works. However on one virtual host i experience some strange
segfaults with the apache since i updated. I will enquire and open a new
bug report since this seems unrelated to this problem.
