Hi,
I have issues on this and not sure what is behind:
My OS: Win7 64 bits
Cygwin installed: 64 bits
Racket: 64 bits
FFI library: 64 bits cygusb-1.0.dll ( it has Cygwin1.dll dependency)
The racket code is very simple, just like below:
#lang racket/base
(require ffi/unsafe
ffi/unsafe/define)
(define-ffi-definer define-libusb (ffi-lib "cygusb-1.0.dll"))
This will crash DrRacket right away, and sometimes even hang Windows.
I check the the Windows event log, it exits with access violation 0xc0000005
error.
I tried other dlls which were installed as packages inside Cygwin, they all had
the same crash issue.
Could you give me some light on this as I don't find anything useful in the
internet?
Thanks,
Roy
