I have an all perl version of FCGI that I made for work called ACGI... seems to work fine. However. I have an ACGI instance that forks child processes, and I put in code to check their exit values using waitpid and $?

When I have freshly started the ACGI, the first waitpid says the exit value was 0 (should be 1), all subsequent waitpids return 255 (should be 0). Any time after that they are all 255

As far as I see there are no end blocks screwing up the value, and an END block I specially put in at the end shows the proper exit values

The ACGI code that I am running is itself a child of a parent ACGI process, so I am thinking that maybe the dual level of forks is the problem, but it doesn't seem that it should be. But as the tests below show, the outer fork does seem to confuse the issue

The box in question is solaris 2.7, with perl 5.6.1...

UPDATE My bad on the test code... see bluto's messages... still have the real problem, tho. The following example is useless

when I run the following one-liner
perl -e 'if(fork){if(fork){waitpid(-1,undef);print"-- ",$?>>8,"\n";}else{exit 4}}'
I get random responses... either 4 or 0... no pattern.

On my debian box with 5.8.2, I always get 4...

and on my redhat box at work with 5.8.0 I always get 0...

Am I going crazy? Did I find a bug? Can I make this work somehow?

UPDATE

ARGH! There WAS and END block and it had system calls in it... damn legacy code full of requires...
