It sounds like something related to GCC 11. The release log does not
show any behavior changes, see
https://gcc.gnu.org/gcc-11/changes.html.

Maybe the linker is performing the whole program optimization due to
LTO and biting you. -fno-lto may help.

If you can identify the function, then maybe you can be surgical and
apply __attribute__((noinline)) to it.
