I am seeing the same issue building with the nRF Connect SDK v2.5.0...

Hmmmm. When I checked the version, my environment was default. When I had the error, I might have been using a different build environment. These are the gcc versions I have on my system beyond 13.2.1....

Those are all the arm gcc versions I have beyond 13.2.1.
At the end of the day, I was able to build and link by removing -Werror from the makefile and it seems to be ok.

[hathach]

what is your git hash, maybe try to update if it isn't latest

Same here,
Using latest GCC

compiles only if I delete -Werror from the makefile

[jgartrel]

It looks like this was introduced as a feature in GCC v12: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105523 .

[jgartrel]

It looks like it can be resolved by adding --param=min-pagesize=0 to the Makefile:
