--- Comment #7 from Konstantin Belousov <k...@freebsd.org> --- (In reply to Greg Lewis from comment #6) First, I am not sure what you mean by 'ther reasons a SIGSEGV could occur in the normal stack region (e.g. a buffer overflow)'. If the region is mapped rw, then SIGSEGV cannot occur on accesses. Second, does JVM use pthread stacks, or is it managing stacks directly by mmap(MAP_STACK) ? If the later, just remove MAP_STACK from the mmap(2) call and see if it is enough. Third, how the guard pages are created ? Do you use mmap(2) or mprotect(2) ? If the later, try to call mmap(MAP_ANON) before doing mprotect(2) on it. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
