short testing yields this :(
[pid 11627] open("/var/lib/php5/sess_0q1md3dakrcv8g2cu083ef6835",
O_RDWR|O_CREAT|O_LARGEFILE|O_NOFOLLOW, 0600) = 6

[pid 11627] fstat64(6, {st_mode=S_IFREG|0600, st_size=0, ...}) = 0
[pid 11627] --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_ACCERR, si_addr=0x8771af7} ---
But maybe I broke the build. Will test again, but that will take 2 days.
