crash on fork in taint mode

[Yohan N. Leder]

Hello. I'm using ActivePerl 5.8.8 build 817 and Apache2 for Windows. The
script below crashes on fork() when I run it in taint mode (not if I
remove -T).

#!/usr/bin/perl -wT
print "Content-type: text/html\n\n";
my $pid = fork();
die "can't fork: $!\n" unless defined $pid;
if (!$pid){print "<p>child in progress...</p>"; exit 0;}
print "<p>parent in progress...</p>";
exit 0;

I don't even get the "can't fork" error message, the script crashes on
the line above with a raw perl.exe exception.

Did you seen something like this ?

Yes,

So, what's the workaround ?

Does building the Perl 5.8.8 for Windows from
<http://www.perl.com/download.csp>, rather than using ActivePerl 5.8.8,
will resolve this fork/taint problem ?

That would very much depend on why you are forking. Particularly
baring in mind that this is windows so you aren't really getting proper
fork() semantics anyhow. Maybe you could use system() or
Win32:rocess.

Looking at the first few hits in the above search would indicate that
it would not.
