LibRaw::open_file() never returns

Submitted by David Partridge on

I've been sent some CR3 files that were reported as causing my application to freeze.

The problem appears to be that open_file() never returns and just sits there eating CPU.

These same files also cause Windows Explorer to freeze for a number of seconds and then Explorer closes and restarts (maybe they're using LibRaw internally to the raw file codec).

I've placed a zip file containing the bad files on Dropbox:

Thank you for the samples.

Thank you for the samples.
Current (github) LibRaw/master rejects these files.

Most likely, the fix is implemented by this commit: https://github.com/LibRaw/LibRaw/commit/cfb66cb2372b373961321cb7ebeae733...
Prior to this fix (i.e. LibRaw 0.20 release), CR3 parse may loop infinite on truncated files.

(we'll release 0.20.1 soon with this fix and couple of other fixes)

Thank you. By soon do you

Thank you. By soon do you mean 1-2 days, or weeks? If the latter I'll pull the latest updates from git.

Thanks again
David

Definitely not 1-2 days,

Definitely not 1-2 days, because we have some not fixed (yet) bugs.

Most likely one week or so.
