I can confirm applying the patches e136a4062174a9a8d1c1447ca040ea81accfa6a8: randstruct: gcc-plugin: Remove bogus void member f39f18f3c3531aa802b58a20d39d96e82eb96c14: randstruct: gcc-plugin: Fix attribute addition fixes the compile issue (on vanilla 6.12, 6.14 and 6.15 kernel trees; the kernels seem to run fine, too, so far). The first patch was needed for the second to apply cleanly. But I can try to backport only f39f18f3c3531aa802b58a20d39d96e82eb96c14 and see if it still compiles. > > This wasn't explicitly marked for stable, but I think a backport would > be good. > > Best regards > Uwe Ingo -- const_cast<long double>(Λ) ^ permalink raw reply [flat|nested] 5+ messages in thread
