hi,
i can confirm this bug and too see segfaults using php5-cli:
a sample backtrace. 3 of 4 segfaults that occoured in the last 16 hours
have been within php_realpath. the remaining one was in T1_CloseLib ()
from /usr/lib/libt1.so.5 while calling the zm_shutdown_gd at
/tmp/buildd/php5-5.2.6.dfsg.1/ext/gd/gd.c:1225
(i do not know if the "gd segfault" is related, so i post this info in
here anyways).
