What happen when I just input a file with ONE picture? about imgify

[jweyrich]

Hi! Thanks for the report! :-)
The input argument (-i) accepts a single file, and that's why open fails with Bad address, since it couldn't access the file you informed. In the sample you provided, it seems that you're informing the path to a folder. Is that right? If so, reading all files from a directory is currently not supported, but it's a feature that I could consider if you can explain me your use case. As a side note, currently, the tool only converts the raw contents of files (binary, spreadsheets, text, whatever) to PNG and from PNG.
Does that make sense?

But I also tried to pass the file to bin2png like this:
root@xxx:/opt/imgify# ./bin2png -i other/not_kitty.bmp -o png_out/out.png
open: Bad address

It also tells me that I got a bad address.

Good news: I believe I managed to get rid of those memory leak warnings.

Bad news: I couldn't reproduce the issue you described. I tried with various files, including the BMP sample you provided.

But I got this...

[jweyrich]

1. Which Linux distribution are you running?
2. Which filesystem it's using?
3. Do you have any FS mount-points related to /opt? In other words, are you mounting /opt (or anything contained in it) from somewhere else?

Looks like the stat syscall is returning EFAULT instead of ENOENT - which is weird.

I use Ubuntu 16 (with Oracla VM VirtualBox, built on Windows 10) and /opt is NOT a mount-point.
