His problem is the same as mine, various commands like '[' segfault bash
(which naturally hoses the startup scripts during install).  No BLODA,
these are running nothing but Windows (Datacenter 2008 64-bit, with the
Amazon EC2Config installed but that's it), and have turned DEP off (and
setting compatibility mode on setup.exe).  It works in 32-bit 2008 AMIs
fine.

I just tried running rebaseall (in c:\cygwin\bin, ash, PATH=. rebaseall -v)
and it rebases stuff, but afterwards scripts still segfault.

The segfault stack dump is as follows:

Exception: STATUS_ACCESS_VIOLATION at eip=76EF930A
eax=00000000 ebx=FFFFFFE6 ecx=00000000 edx=00000000 esi=FFFFFFFF
edi=0027C6E8
ebp=61226084 esp=0027C69C program=C:\cygwin\bin\bash.exe, pid 2224, thread
main
cs=0023 ds=002B es=002B fs=0053 gs=002B ss=002B
Stack trace:

End of stack trace

Thanks,
Ernest
