Corinna,
I've been trying to figure out why cygwin isn't working properly on
Vista x64. I saw the thread you posted to here:
http://www.cygwin.com/ml/cygwin/2006-11/msg00595.html
I see that cygwin is performing the trick outlined here:
http://www.catch22.net/tuts/undoc01.asp
(Search for "Pass arbitrary data to a child process!")
This is achieved because the child_info class is declared to have:
DWORD zero[4]; // must be zeroed
It appears as if this trick is no longer working under Vista x64. The
question is, does this code now have to resort to using
VirtualAllocEx/WriteProcessMemory, or is there a way around it?
Have you been able to isolate this into a simple binary test? I am
currently running on a Vista x64 system right now with VS2005
installed in case you would like me to try out anything which may be
of help.
-Andrew
