>Description:
When building gtk4 on a -current system with gcc 12 and

PKGSRC_USE_RELRO=       full

in /etc/mk.conf (you'll have to comment out "RELRO_SUPPORTED= partial"
in x11/gtk4/Makefile), there is a core dump of Gdk4 during the build.

The problem with the package is tracked in PR 57792, but Rin Okuyama
requested a separate bug report for the toolchain.

>How-To-Repeat:
Comment out "RELRO_SUPPORTED= partial" in x11/gtk4/Makefile, add
PKGSRC_USE_RELRO=       full
to /etc/mk.conf and try building x11/gtk4 on -current with gcc12.
