[Bug 236714] Clang problem with rctl(8)
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=236714
--- Comment #12 from Mateusz Guzik ---
It is not being ignored. There is non-zero garbage in an area not written to by
sysctl, which makes the zero comparison fail.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=236714 --- Comment #11 from Edward Tomasz Napierala --- Patch looks good, thank you! What about the underlying issue, which is sysctl(3) silently failing when it receives an improperly sized buffer? Would it be feasible to make it return an error, so it's easier to fix next time it happens? -- You are receiving this mail because: You are the assignee for the bug. ___ freebsd-toolchain@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-toolchain To unsubscribe, send any mail to "freebsd-toolchain-unsubscr...@freebsd.org"
[Bug 236900] lang/gcc8: BOOTSTRAP=off fails to build after r497254
