https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=241905 --- Comment #6 from Kyle Evans <kevans@freebsd.org> --- (In reply to Konstantin Belousov from comment #5) Huh, today I learned about __constructor__ priority, too. =-) It looks like it's really only one __constructor__ creating a thread, and that constructor is using whatever the toolchain default is: https://github.com/qemu/qemu/blob/master/util/rcu.c#L376 I guess this is the same as __guard_setup, https://svnweb.freebsd.org/base/head/lib/libc/secure/stack_protector.c?revision=332940&view=markup#l47 -> I can bump the priority on qemu's to 200 and that sufficiently works around the problem, but it seems like __guard_setup should be specifically lower than the default. -- You are receiving this mail because: You are the assignee for the bug.home | help
