Making the brk start exactly at the end of the main application binary was requiring to get it through the _end symbol, which does not work any more with recent toolchains, and actually produces in libc.so a confusing external _end symbol that produces odd results, see https://sourceware.org/bugzilla/show_bug.cgi?id=23499 Trying to do so is quite outdated anyway with the tendency for address randomization. Using _end was also allowing to include the main binary data within the RLIMIT_DATA, but this also seems outdated with dynamic library loading, and nowadays' memory consumption via malloc and mmap rather than statically-allocated data. This adds a BRK_START macro in <vm_param.h> that just tells where we want to start the brk, and thus removes the _end symbol. * sysdeps/mach/hurd/i386/vm_param.h: New file. * sysdeps/mach/hurd/brk.c: Use BRK_START as brk start instead of _end. Also ignore __data_start. * hurd/Versions: Remove _end symbol. * sysdeps/mach/hurd/i386/libc.abilist: Remove _end symbol.
