cygwin, though I don't believe it is related.
perl-5.8.8 and perl-5.10.0
Win32-GUI-1.05
scripts\win32-gui-demos.pl and Win32-GUI-Scintilla\demos\Editor.pl
crash. The first after starting an app, the 2nd immediately.
This came from the cygwin list, with Vista, but I and others can reproduce
it with XP2. Looks like an Scintilla.xs problem.

(gdb) x stash
0x1: Cannot access memory at address 0x1

Reason: Someone is overwriting the stash with 1,
and the perlud name is also wrong.
It should be "Editor", not "or"
So I believe the stack is corrupt at all.
