Bug ID: 167572
Summary: gtk4 VCL crashes immediately with free(): invalid
pointer
Product: LibreOffice
Version: 25.2.5.2 release
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: LibreOffice
Assignee: [email protected]
Reporter: [email protected]
Description:
When launching LO using the GTK4 renderer it errors and crashes immediately.
This has been occurring for many releases. Not sure I've ever seen it
functional.
Same crashing behavior under Gnome, Sway, and Hyprland.
I always delete ~/.config/libreoffice prior to reproducing any issue.
NOTE: This is a pure native Wayland environment without Xwayland.
Attaching GDB backtraces.
