Hmm.
dc_device_foreach is in libdivecomputer, and is a rather simple function.
I suspect that "device->vtable" is NULL.

The caller is do_libdivecomputer_import -> do_device_import, but do_device_import is likely inlined.
I'm not seeing how device->vtable would be NULL, but it's either a libdivecomputer bug, or it is, as you say, memory corruption.

I can also confirm an issue in windows 10 as well when using the older serial port method to download from a petrel 2.
I don't remember the exact error message and when I tried again from command line using -vvv to capture the messages it worked successfully.
