[Bug] Crash when using a custom backspace key in the pattern editor

[malespiaut]

Operating System

Linux

What's the issue you encountered?

ImHex crashes when I use my custom backspace key in the pattern editor.
I use a custom keyboard layout, under X11, that replaces the key B (AB05) with Backspace.

How can the issue be reproduced?

Open a file.
Go into the pattern editor.
Remove the backslashes of a comment using the custom backspace key.

ImHex Version

1.39.0.WIP-Debug master@70fdbd4a489aa32735e9b7104f5431a9a745eb8d

ImHex Build Type

• Nightly or built from sources

Installation type

git clone + compiling a debug build myself

Additional context?

I'm using Arch Linux, with kernel 6.18.6-zen1-1-zen.

I hoped to have information about the backtrace, so I compiled the project using cmake -S . -B build -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_FLAGS_DEBUG="-O0 -ggdb3" -DCMAKE_CXX_FLAGS_DEBUG="-O0 -ggdb3" -DCMAKE_C_FLAGS="-O0 -ggdb3" -DCMAKE_CXX_FLAGS="-O0 -ggdb3", but it didn't help.

When crashing, ImHex displays the following:
