Failed to dup STDIN: Bad file descriptor.

[Rashmi Badan]

Hi,

I load mod_perl into a customized Apache on Windows but when I send a
simple request (http://host:port/perl/testperl.pl - testperl.pl just
prints a simple message) Apache dies and throws the following message
in the error log

Failed to dup STDIN: Bad file descriptor.

I see that this is coming from modperl_io_perlio_override_stdin() in
modperl_io.c but do not know why. If I try loading the same module
into plain Apache I don't seem to hit this problem and am able to
access the script just fine. I would appreciate it if someone could
give me some pointers to debug this issue.

Versions used :
Apache 2.2.9
mod_perl 2.0.4
perl 5.10

mod_perl.conf.

LoadFile  ${PERL_PATH}/bin/perl510.dll
LoadModule perl_module modules/mod_perl.so
