Description of the bug

I loaded the official Benchy STL model. I then rotated the model by 45 degrees. Selected Organic Supports, then slice. Program crashes are repeatable.

I was using tool 2 on my E3D Toolchanger profile.

If I select T0 I can export a file. Selecting T1 results in a crash. There is a grey "Invalid Data" at the bottom right of the application.

Project file & How to reproduce

I loaded the official Benchy STL model.
Rotate the model by 45 degrees in Y and 180 in Z.
Selected Organic Supports.
Select Tool 1 (T1 or tool head 2) , then slice.
The program crashes at this point.
I can't grab a screenshot, the program exits.

I have the same issue with multiple extruder. Slices fine on tool 0 but crashes during slicing on others. Here's a 3mf with a benchy that showed this behaviour

@mann1861 Thanks, but I cannot reproduce it. Your 3MF slices fine on my system in 2.5.0 and 2.6.0-alpha2, regardless of the selected extruder. Can you please check that the 3MF indeed captures the crashing scenario or possibly include a short video showing all the steps between starting the application and the crash? Thanks.

Choosing toolhead 1, then selecting toolhead 2. Crashes on T1 but not T0. Slicing organic supports. When it crashes, application exits or has invalid data displayed.

@terryrobison Thanks, but still unable to reproduce it. I need the 3MF which I asked for.

I took one of your previous 3mf and have followed your videos. The issue is reproducible with direct crash or error message Acess violation...
I think this issue is duplicite of #9550
I am closing it.

Fixed an UB in CoolingBuffer.cpp: uninitialized var in case that std:…

…:from_chars fails:

This fixes CoolingBuffer behavior wrt. 2.5.0 in cases where custom G-Codes contained
lines starting with "T". Those were previously considered as valid toolchanges.
In 2.6.0-alpha3, this scenario led to a hard crash: #9470, #9550
