Summary: CLI segfaults when trace file is not writeable
Description:
A script lets xdebug write a tracefile. Executed via Apache, xdebug sets
owner.group of the tracefile to those of Apache (www-data.www-data on
Debian) and permissions to 644.

Executing the same script via PHP CLI segfaults w/o any useful info.
Strace shows its because the tracefile is not writeable. CLI executes as
current user, which is not www-data.

It would be nice if xdebug terminates gracefully with an explanatory
message instead of crashing ;)

Here's strace's last lines:

open("/tmp/init-parenchym.php.xt", O_RDWR|O_LARGEFILE) = -1 EACCES
(Permission denied)
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++
