https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=228574 --- Comment #3 from Mark Johnston <markj@FreeBSD.org> --- Looks like the binutils maintainers consider our use of _end to be a bug: https://sourceware.org/bugzilla/show_bug.cgi?id=23161 I don't see how we can implement brk()/sbrk() without it though. Looking at glibc, they initialize curbrk using a seemingly undocumented kernel interface: on Linux, the brk() system call returns the current break address if the input break value is 0. Our SYS_break system call currently does not have a return value... perhaps the right solution here is to add a similar hack and use that in libc to initialize curbrk. -- You are receiving this mail because: You are the assignee for the bug.
