New Comment:
Sounds like some is taking over the handler for the SIGPROF and it
never gets to PHP. Besides PHP, what modules/extensions do you have
enabled in your Apache?

Works on FreeBSD 4.x (with unmodified PHP source).
So it's kind of Solaris-specific (will test on Sparc)

[oops, posted this as "add comment" because I hadn't read the direction
to use "edit submission" instead yet --sorry]
Just out of curiosity, and admittedly not quite understanding what I
was doing, I have tried changing the zend_set_timeout code to use
SIGALRM instead of SIGPROF and thus pass ITIMER_REAL to setitimer
instead of ITIMER_PROF
Guess what? It works now.
I understand that this can have nasty side effects. I was just
wondering why SIGPROF was being used and if this could be the reason.
The setitimer man page on Solaris says a lot of things about using it
in MT environment which I don't quite catch :-)

Just tried with php4-200212160830 (4.4.0-dev): same, the script never
exits.
I'm compiling this on Solaris 2.7/SPARC and FreeBSD 4.5 to see how much
O/S & platform specific this problem is.
I've added a
zend_printf("zend_timeout<BR>\n");
to zend_timeout() (Zend/zend_execute_API.c). I can see the message in
the browser when timeout works (like when running in Apache 1.3) but
not when it doesn't (although my loop.php script now exits after a huge
for loop so that I can see the page output). So I presume that the
signal triggered by setittimer in zend_set_timeout() is never
delivered.
Thanks for the impressively fast reply!
