Subject: gcc ICE while building landlock
Hi,
On 6.15-rc1 (with a few more code deletion patches on top),
I'm seeing an ICE while building landlock with an allyesconfig
on Fedora 42 x86-64 gcc:
make -j 32 KCFLAGS="-Wno-error=unterminated-string-initialization -Wno-error=sequence-point -Wno-error=unterminated-string-initialization"
