I tried to reproduce your problem using the DJGPP port of Perl 5.005_02
(perl --version, I think it's the same as yours) and bash 2.03, 2.04 on
Windows 98 SE. It didn't crash for me in these variants:

    perl -n -e '`$_`'
    perl -e 'while(<>) { `$_` }'
    perl prog.pl

with prog.pl containing your program. I tried in a directory with no
spaces (c:/temp) and one with spaces (c:/Program\ Files). I get "Bad
program of filename" errors.

Do you only have DJGPP's port of Perl installed? What does 'type -a perl'
display from bash? Maybe there's something bogus set in your environment?
What does 'env' display from bash?

Bye,
