When did it start failing? What changed?

alexlib commented 6 years ago

It appeared today on Ubuntu 14.04. Not clear what changed. maybe an upgrade to gcc with all the upgrades of Ubuntu.

alexlib commented 6 years ago

it doesn't appear on Mac OS X

I've had a similar experience yesterday. Test check_multimed.c started failing, but not always, and after a while started passing which makes it hard to debug. I have done some investigating, haven't found an answer yet. But I think it can't be a buffer overflow, because efence should catch that. Maybe a better candidate is reading uninitialized memory somewhere. Probably in the parameters or calibration reading code, which multimed and imgcoord should share.

maybe it's all the same ? Now I do not have failures on Ubuntu anymore - see #152
