[IPOL discuss] Software crashes

[eml]

Dear Pierre,

The exact input images are not directly known.  However, we have the
exact time of the crash, and from that and the output "ls -ltrd
/srv/ipol/demo/app/*/tmp/*" on the demo server we can recover the
temporary directory of the demo instance that produced the crash.

I, for one, am guilty of the crashes in the viewflow program.  In
fact, it is the error message on viewflow that triggers (on purpose) a
segfault.  The error comes from an empty input produced by the optical
flow computation, where the program occasionally fails.  I have not
been able to reproduce this error.

regards,
enric
