enfuse: Can not read TIFF directory count

[nobody]

I was stitching a LARGE panorama (60+ input images, HDR). Hugin had spent at least 15 minutes rendering using all four processors at 99% capacity. When I got back after dinner it had crashed with the message that I should report the crash here. This is the error message I got:

I tried it again, keeping an eye on Activity Monitor. The process using the CPU was "nona", and it used between 30 and 100% of my computer (quad-core MacPro). Free memory (6 GB installed) varied between 39 MB and 2.97 GB. I was runnign nothing except Hugin and Activity Monitor.

Second crash looked like the first:

Hi the tool that crashed was 'enfuse' which was trying exposure blend six images together - Does that sound right? six is an odd (even) number of brackets.

Even so it shouldn't crash, have you checked that there is enough disk space during the stitch? hugin may be using a different disk for temporary files than you expect.

[rew (r-e-wolff)]

Bruno, the weird number (6) for the exposure occurs because the user probably took a full 360 degree pano, ending nicely aligned on the first images after taking 3x19 pictures in between at 18 degree intervals.

Should blending a double stack work?

Should a warning be printed? (One stack is 6 high, all the others only 3!).

It seems that nona wrote an invalid tiff file. If this didn't work at all, we'd see nobody getting results on MacOS. So I suggest closing this bug. The questions above warrant a new one about the double stack.
