leonidlm has asked for the wisdom of the Perl Monks concerning the following question:

Hi all,
I run into a strange error while using the Win32::File::Ver module using the GetFileVersion method.
The perl.exe just crashes when reaching the following line of code:
$hashRef = GetFileVersion($fileName);
I tried to use the ptkdb debug module and step into the method but it crashes even before showing me the method code!
Help me plz :)

      Os - Windows 2003 $fileName - c:\run.dll
      Thx.

        I just ran the latest version from cpan against 2500 files, 1800 of which are executables, and it either report the data or returned undef.

        There must be something strange about that file. Did you compile Win32::File::Ver yourself or get it as a PPM?


        Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

[Corion]: On the upside, I spend a lot of time thinking this weekend about how to actually implement rate limiting for futures, and if things work out, maybe even loading a configuration from an external file makes sense
[Corion]: I've also found some interesting invariants that I have to think/write about more. A simple rate limiter will never change the order of the input, while a limiter that allows for parallel execution will change the order. But my API currently allows for bo
[Corion]: ... for both, and I'm not sure if I want to add the cruft from the parallel API (a token that you need to hold on to while you hold the lock) to the rate limiting API too, to allow seamless up/downgrades, or not.
[Corion]: Also, rate limiting will look great with await: my $token = await $limiter-> limit($hostname); instead of my $f = $limiter->limit( $hostname )->then(sub { my( $token)=@_; ... });
