Hello Superfox il Volpone,

I get no infinite recursion on my system (Windows 8.1, 64-bit):

16:17 >perl 1215_SoPW.pl
Hello world 1 aaaaaaa
STDOUT: GLOB(0x1c94bc8)
STDERR: GLOB(0x1c94c28)
handle: GLOB(0x55c2d8)
Hello world 2 bbbbbbb

16:17 >perl -v

This is perl 5, version 20, subversion 2 (v5.20.2) built for MSWin32-x
+64-multi-thread
...
[download]

(Strawberry Perl, portable.)

Hope that is of interest,
