This bug looks like a duplicate of both bug #41699 and bug #40443. I can reproduce the crash with the provided example, or with the following:

imformats
clear -f

There has been progress in fixing this on the development branch, see the other bug reports. Closing this one as a duplicate.

I found antoher way to trigger the same bug. (same stack trace as before)

imwrite(randn(800,600,3),'photo2.tiff');
clear -f

Please add a backtrace.
In gdb, after the segfault do:

I started the gdb.exe octave-gui.exe and the last output reads as follows. Maybe this is helpful.

Program received signal SIGSEGV, Segmentation fault.

It's very probably the notorious "clear all" bug that's popping up.
Just google for '"clear all" octave bug' and you'll see reports dating back from 2008. AFAIU it manifests itself especially on MinGW but looking at the bug reports tru google it seems linux builds are also affected.
I couldn't find an explicit bug report for it. But I'm fairly certain this is a duplicate. Marking as "confirmed" for the time being.

My Octave-3.8.0 (another build than the one from Markus), running on XP, disappears from sight as soon as the first "clear all" statement is executed.

It used to be related/caused/triggered by certain OF packages, but on my box this "crash" happens w/o any OF package loaded.
After a fresh restart of Octave, "clear all" appears harmless. Only after having executed certain instructions/functions/commands the bug condition is triggered and a "clear all" command makes Octave disappear.

The bug can be avoided by invoking the clear command w/o the "all" parameter.

I encountered a bug, that crashes GNU Octave without giving me any hint to why it crashes. The program windows just disappears. No error message, no MS Windows error report, nothing.

Steps to reproduce:
1. Use Windows. (GUI or CLI doesn't matter)
2. Create a script with the content below.
3. Run the script. (I.e. using F5 in the GUI)
4. Observe that octave is closed without any error message.

imwrite(randn(800,600,3),'photo2.tiff');

clear all;
A=imread('photo2','tiff');

clear all;
A=imread('photo2','tiff');

It's actually the second repetition that triggers the bug. Doesn't matter if it is in a single script like in my example here, or if I would call a similar script twice.

I tested it on my own Linux-build and there it works fine, so it's Windows specific.

I use the build form http://mxeoctave.osuv.de/octave-3.8.0-4-portable.7z

So there are two questions:
a) What is the error?
b) Is there a crash handler that could help diagnose the problem (i.e. running with gnu debug gdb ? )
