Crash on PBC execution under Windows Server 2003

[mvuets]

The crash happens on Rakudo, abc and several other languages. I'll show an example with abc.pbc.

If i pass a source file---parrot just silently finishes.

C:\Parrot-1.3.0\bin>echo 1+2 >test.bc
C:\Parrot-1.3.0\bin>parrot.exe ..\lib\parrot\languages\abc\abc.pbc test.bc
C:\Parrot-1.3.0\bin>

If i enter a code interactively---parrot crashes.

C:\Parrot-1.3.0\bin>parrot.exe ..\lib\parrot\languages\abc\abc.pbc
> 1+2

parrot.exe - Application Error

I believe i know a reason of the crash. I don't know how Parrot works in fact, so my assumption is that it translates PBC into native instructions (JIT) and places given code into RAM, then it executes it directly from RAM. It is data execution and it may be disabled on Windows (called DEP) to prevent of exploits.

I just disabled DEP and now Parrot works normally. This information must be added to some README or FAQ.

See  KB 875352 and  KB 912923 for details about DEP.

Is there anyone who can provide an update on this ticket?

If not, I'm inclined to close it as WONTFIX because I don't think we have a commitment to support seven-year-old Windows server technology. (Anyone who wants to overrule me should take the ticket!)

Thank you very much.

I'd like to support Windows Server 2003 if possible, but we'd need someone who could (at least) regularly test on it. Until we find such a person, I don't feel bad marking this ticket as wontfix.
