At least I know that it is not only mine / osx case. While the crash is in the libusb and should probably be fixed there (I mean the lib code shouldn't crash even if abused ;-) it seems to be the VICE's fault to trigger the bug by some erroneous call or something. i think so because the OpenCBM tools seem to work all fine. > > > I've tested the Windows OpenCBM with VICE in the past, and it worked ok.

Sorry to follow up so quickly, but it could also be a 64-bit problem. The area reserved for the OpenCBM CBM_FILE HANDLE object may not be treated properly by VICE. It needs to compile to an intptr_t (64-bit or 32-bit addresses, depending on platform). If VICE assumes it's an int or does casting, that could be the problem. -Nate Message was sent through the cbm-hackers mailing listReceived on 2012-12-06 20:01:02
