Long story short\, I was able to boil down the problem to a single line (hehe). The perl -e command runs fine on linux\, but returns a compilation error on Windows.

command line perl -e "\$err=256>>8;print\"Error​: \$err\n\";"

Linux Output​: yor_mgra@​yors0353​:\~> uname -a Linux yors0353 2.6.18.8-0.7-default #1 SMP Tue Oct 2 17​:21​:08 UTC 2007 x86_64 x86_64 x86_64 GNU/Linux

yor_mgra@​yors0353​:\~> perl -e "\$err=256>>8;print\"Error​: \$err\n\";" Error​: 1

Windows Output c​:\>perl -e "\$err=256>>8;print\"Error​: \$err\n\";" Can't modify single ref constructor in scalar assignment at -e line 1\, near "8;" Execution of -e aborted due to compilation errors.

Are there any ideas about this\, as this would seem to be a bug with the Windows build?

It's just a Windows cmd.exe quoting thing. The following one-liner has the same error​:

perl -e "\$a=0"

The Windows shell is actually passing \$a=0 (rather than $a=0) to the Perl interpereter\, which causes the obvious error.

This is fine​:

perl -e "$a=0"
