Perl is compiled with LFS enabled, and uses a 64-bit "off_t"; Apache is compiled without LFS, so uses a 32-bit off_t. The impact of this problem seems surprisingly (but thankfully) limited, there is one reference to it in docs/api/mod_perl-2.0/APR/PerlIO.pod: seek($fh, $offset, $whence); If "$offset" is zero, "seek()" works normally. However if "$offset" is non-zero and Perl has been compiled with with large files support ("-Duselarge- files"), whereas APR wasn't, this function will croak. This is because largefile size "Off_t" simply cannot fit into a non-largefile size "apr_off_t". I don't expect there is much we can do about this, but worth noting the problem.
