Konsole Crashes When Zooming In

[Strbean1]

Steps to reproduce:

1. Open amp in Konsole
2. Use Ctrl+Scroll to Zoom in and out

I either get this error:

user-pc% konsole
HistoryFile::add.write: Bad address
zsh: segmentation fault (core dumped)  konsole

or this:

user-pc% konsole
corrupted size vs. prev_size while consolidating
zsh: abort (core dumped)  konsole

Any idea why this happens? Should I report to KDE instead?

I managed to recreate the crash, just wildly zooming in and out while Amp is open with a file.

This seems like some sort of memory corruption inside of Konsole. Thus I think reporting to upstream KDE is the way to go, seems like a very weird issue to me.

I've captured multiple backtraces + full core dumps from the crash. If needed, I can gladly chime in on the KDE bugtracker and help figuring this out.

Below is one backtrace, which you can use when reporting to KDE. This was on a fully up-to-date Arch Linux box (konsole 21.04.0).
