Could you do that again, but this time type the following after you
type "bt" (also in gdb):
frame 2
print *stream

I was using 4.3.0 on the machine running the "server" test script (but
since that script is merely to aid in testing the bug in the "client"
script, I didnt think it mattered). The machine running the "client"
script - the one experiencing the bug - was running a stable snapshot
compiled last night. Nontheless, I just re-compiled with the latest
stable today, ran again, and managed to generate a bt in the process:
#0 0x420e19ee in select () from /lib/i686/libc.so.6

Are you using the 4.3.0 release or the latest stable snapshot? (the
version field above and the version you mention in your comment don't
seem to match up).
If you're using the released 4.3.0, please try the latest stable
snapshot from snaps.php.net first.

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php
Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.
Run the cli under gdb (see instructions above),
and when it hangs press CTRL-C.
You can then type "bt" to generate the backtrace.
