-lc & -specs=nosys.specs cflags seems to "fix" this — so qmk compile -kb preonic/rev3_drop -km default -e CFLAGS+="-lc -specs=nosys.specs"
I suggest joining the QMK discord server and reading through this thread.

[stalkerg]

@waffle87 seems like QMK doesn't support the latest GCC, am I right? Do you have a ticket for such an issue?

[waffle87]

GCC 12? It does. Bugs related to it have been fixed for some time now.
qmk_firmware/17064
pico-sdk/840 (only relevant if using RP2040)

[stalkerg]

@waffle87 no, it's gcc 11

[stalkerg]

Fixed by:

qmk compile -kb preonic/rev3_drop -km default -e EXTRAFLAGS+="-U_FORTIFY_SOURCE"

It's needed because the Gentoo GCC, by default, enables the SSP (FORTIFY level 2) for any tasks with optimization.
The current QMK printf implementation doesn't support overwiting the SSP version.
