I am quite positive this has been fixed in CVS already. For instructions on how to use the CVS version, see: http://xdebug.org/install.php#source

And as I see now, the same is true vice versa: CLI creates trace file, Apache is denied to overwrite it, child process segfaults.

(PHP Version is 5.2.2-1+b1)

It's not. I just compiled the sources of 2.0.0RC4-dev and had the same bug as described above.

Besides, make test reports:
Number of tests : 87 69
Tests skipped : 18 ( 20.7%) --------
Tests warned : 0 ( 0.0%) ( 0.0%)
Tests failed : 69 ( 79.3%) (100.0%)
Tests passed : 0 ( 0.0%) ( 0.0%)

Time taken : 22 seconds

AHEM?

I can not reproduce this:

derick@kossu:/home/httpd/html/test/xdebug$ cat bug267.php
<?php
xdebug_start_trace("/tmp/bug267test");

strlen( join( ", ", range( 1, 10 ) ) );
?>

derick@kossu:/home/httpd/html/test/xdebug$ php bug267.php

derick@kossu:/home/httpd/html/test/xdebug$ ls -l /tmp/bug267test.xt
-rw-r--r-- 1 derick derick 328 2007-05-22 22:36 /tmp/bug267test.xt

As you can see it did not overwrite the file, but instead saw that the file was not writable and created a file with a random bit in it; and no segfault.

When using autotrace:

derick@kossu:/home/httpd/html/test/xdebug$ php -dxdebug.auto_trace=1 bug267.php

derick@kossu:/home/httpd/html/test/xdebug$ php -dxdebug.auto_trace=1 bug267.php

derick@kossu:/home/httpd/html/test/xdebug$ ls -l /tmp/*.xt
-rw-r--r-- 1 derick derick 406 2007-05-22 22:45 /tmp/trace.1258863198.xt

derick@kossu:/home/httpd/html/test/xdebug$ sudo chown root /tmp/trace.1258863198.xt

derick@kossu:/home/httpd/html/test/xdebug$ php -dxdebug.auto_trace=1 bug267.php

derick@kossu:/home/httpd/html/test/xdebug$ ls -l /tmp/*.xt
-rw-r--r-- 1 derick derick 406 2007-05-22 22:45 /tmp/trace.1258863198.042ab7.xt
-rw-r--r-- 1 root derick 406 2007-05-22 22:45 /tmp/trace.1258863198.xt

Thanks for describing that procedure. I copied that step by step and again got that segfault. Hmm...

Checked out your latest sources, which are RC5-dev, and :) xdebug works as you described.

Well, it seems xdebug creates a new file every time, even if it could overwrite the last one. -- Which makes perfectly sense, 'cause that random part in the filename is, well, random. But over time it would fill up my tmp space...

Thank you for xdebug

Cool, let's close it then.
