The snapshot window crashes me reproducably.

Just open it and click cancel or use the [x] in the top right -> crash.

Hi Henri.

Something isn't working as it should with 1.26.8.13 for me. (1.26.8.12 works just fine.)

As you know I compile your sources myself with only two changes: Turning tcmalloc back on (switch in 00-Common.cmake) and reverting to libpng 1.2 instead of 1.5 (edit of install.xml for sources, and changing version call in PNG.cmake) as Debian still uses 1.2.

Here is reproducible steps for me:
1. Take snapshot
2. Save as file, select file name and folder and hit save.
3. Segfault.

It works normally with the previous source, and both versions has been compiled on a *clean* tree in an empty folder in case you wonder if I learned my lesson. ;)

Log file, stack trace and GDB output attached.

I can add it seems related to the thread about 1.26.9.13 crashing when snapshot floater is closed. It happens here too.

Console spits out one more clue:
Code:
./cool_vl_viewer: line 159: 18552 Segmentation fault

(The five numbers varies, but it always refer to line 159.)

And if I save a snapshot the segfault happens after the file is saved to disk.

I hope it helps the debugging ;)

Aha, see I have this crash in the snapshot window too, but all I do is open and close the window. I don't even save to disk.

Ouch !... yes, quite a nasty bug that I surprisingly didn't come across myself before publishing last releases... I'll publish emergency bugfix releases ASAP.
