I've heard that this was fixed in PHP 5.3.5. It's not listed in the release
notes
from what I can see, so can someone confirm if 5.3.5 addresses this issue?

I've been trying to track down this file descriptor leakage problem for months.
I was stuck on 5.2.8 because of it. I confirm that the issue is specifically
with Solaris 10. I have opensolaris sxce nevada 130 locally and I've not seen
FD leakage on it.
I confirm that patch suggested by bryan at stansell dot org seemed to correct
the problem. FYI, PHP was spawned and remains persistent for use with the
Litespeed web server (uses the LSAPI interface), so it would run out of file
descriptors between 1 and 12 hours on my site. It's a bit disappointing that
this error has been present for 5 releases and was never fixed.

I finally got a chance to test a theory. Looks like the volatile attribute
fixed things for me.
#if HAVE_BROKEN_GETCWD
volatile int old_cwd_fd = -1;
#else
Once I added that, the setjmp/longjmp worked as expected. I got the idea from
the manpage on Solaris:
The values of register and automatic variables are unde-
fined. Register or automatic variables whose value must be
relied upon must be declared as volatile.
Perhaps it's a gcc/gas/Solaris/x86 optimization somewhere that overlooked the
case, but this is a workaround. Of course, undefining HAVE_BROKEN_GETCWD for
Solaris also works, if you have a web tree that isn't restricted in some way.
