I frequently get drastic errors (my computer shuts down!) when I try to
use backticks.
and I replied:
I do this in nearly all of my perl scripts - at least once. Here'some
code.
my $status = `dir 2>&1`;
Output (Stdout & Stderr) are both captured in the $status variable.
Hope this helps, (and I hope that's what you were asking)

The output from the "dir" command.

Ahhh.....look at what you're trying to do here. You're launching an
instance of perl by running the
script which has the above code. Then, in your code, you're launching
another instance of perl.exe.
I suspect that this is what is crashing the machine...BUT...
I took your code and tested it and it ran fine. Methinks there is
some other instability on your machine or in your code. Maybe uninstall
Perl and
re-install? Maybe try to determine where exactly in the script it
crashes? Might
not be crashing on that command at all...
