apache-1.3.36 perl-5.6.1 Apache::ASP-2.59 problem

[Thanos Chatziathanassiou]

(Hate to reply to my own mail, but...)

for reasons I cannot figure out yet, this part of Load.pm doesn't quite
work as expected:
---snip---
opendir(DIR, $file) || die("can't open $file for reading: $!");
my @files = readdir(DIR);
close DIR;
---snip---

@files contains as many elements as files in $file (which in this
context is actually a directory), but instead of filenames, they contain
the empty string. Which of course leads to the deep recursion/out of
memory error, given a directory with enough files.

Still don't get why this happens though.
And furthermore, why it works with 1.3.34 (all other things being equal
- perl - mod_perl - Apache::ASP version etc) and doesn't on 1.3.36

Indeed that was the culprit and using glob instead of readdir provided a
workable solution.
However, apache 1.3.37 was released in between and I decided to build
this one instead. With the same perl version (5.6.1), same mod_perl
(1.29) readdir worked as expected.
BTW, all apache versions were compiled from sources using the same
script (with changed paths) with gcc-2.95.3 against glibc-2.2.5.

Still can't figure out what was wrong with 1.3.36 compared to 1.3.34 &
1.3.37 though.
There's nothing even remotely related in the Changelog and I haven't
mustered the courage to do a diff between them yet... Still, I think we
can leave it be for now.
