Bug ID: 171380
Summary: immediate crash (free(): invalid pointer) on wayland +
opencl + VCL not gtk4 + not launched via "startcenter"
Product: LibreOffice
Version: 26.2.1.2 release
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: graphics stack

trace generated using "libreoffice --calc --backtrace"
platform: Arch linux
package version: 26.2.1-2
(bug not present in 26.2.0-4)
when starting any $APP in {writer, calc, draw, impress, base, global, math,
web} using "libreoffice --$APP", the empty loading bar appears, disappears (the
bar never moves), and the application crashes with the following message:
free(): invalid pointer
Unspecified Application Error
now, following the guidance from
https://wiki.archlinux.org/title/LibreOffice#LibreOffice_freezes_or_crashes , I
tried a few things, all of which seem to "solve" the problem; launching the
application in the following ways does not crash them:
---
launching the "startcenter" and selecting the desired application
"GDK_BACKEND=x11 libreoffice --$APP"
"SAL_DISABLE_OPENCL=1 libreoffice --$APP"
"SAL_USE_VCLPLUGIN=gtk4 libreoffice --$APP"
---
however, specifying any other SAL_USE_VCLPLUGIN other than gtk4 still results
in a crash,
even tho gtk3 and qt5 are available on the system.
It seems like for the invalid free() to occur, _all_ of the following need to
be given:
* on wayland
* VCL not gtk4
* opencl enabled
* not launched via the "startcenter"
tracelog is attached
