Package: php5-cgi
Version: 5.2.6.dfsg.1-1+lenny3
Followup-For: Bug #549492
I'm having quite frequent segfaults (1 out of 100 requests) via php5-cgi
(behind Apache2 + mod_fcgid). Traced widh php5-dbg + gbd, all traces look
the same, _zend_hash_add_or_update with arg arKey="REMOTE_ADDR" all the
time:
Program received signal SIGSEGV, Segmentation fault.
