UFRaw 0.18 with GIMP 2.6.12, Windows XP SP 3.

When I start the 16 Bit- TIFF- conversion of a directly before loaded CR2-file from my Canon 5D MkII, which has very large raw-files (5634 x 3753 pixel), UFRaw begins Interpolating, stops it at 98 percent or so and then crashes with the message "ufraw.exe has encountered a problem and needs to be closed" etc. or so. Then I saw, that UFRaw has created a TIFF-file with only 1 KB, but no ID-file (“Create ID-file”- option was set to “also”). This 1 KB- TIFF-file cannot be opened by any Image viewing- or Image manipulationg program. When “Create ID-file”- option is set to “only”, UFRaw creates an ID-file. When I then load this ID-file into UFRaw-batch, the result is the same as described above (crash, error-message, undecodable 1 KB- TIFF- file).

With JPG- or 8 Bit- TIFF- output, UFRaw works normal.

I made several attempts with cropping the raw-image at its left side by using the crop-and-rotate-tab, then started the 16 Bit-TIFF- conversion and saw, what happens.

Results:

1.) Image cropped at its left side so that image dimensions are now 5049 x 3753 pixel: UFRaw begins Interpolating, stops at 99 percent or so, then UFRaw disappears from the desktop without any message. UFRaw has created a TIFF-file with only 1 KB, but no ID-file (like described above).

2.) Image cropped at its left side so that image dimensions are now 4999 (or smaller) x 3753 pixel: UFRaw works normal.

In all these results, it makes no difference, which interpolation algorithm is chosen.

    I can confirm the crash with UFRaw 0.19.1 (32-bit installer) on Windows 7 (64-bit), but UFRaw works as expected on both 32-bit and 64-bit Linux.

    New attempt with UFRaw 0.19.1 on Windows XP SP3: Same crash, identical behaviour as reported initially.

    It was actually a stack overflow. It seems that the win32 stack is too small. This is now fixed in CVS.
