The lang/gcc6-aux build relies on a pre-built binary bootstrap compiler. It appears this needs to be recreated for ino64. Trying to build with the BOOTSTRAP option set results in the same sort of failure as in the exp-run. http://pb2.nyi.freebsd.org/data/headamd64PR218320-default/2017-04-05_20h35m39s/logs/errors/gcc6-aux-20170202_1.log mkdir -p ada/bldtools/sinfo rm -f ada/bldtools/sinfo/sinfo.ads ada/bldtools/sinfo/sinfo.adb ada/bldtools/sinfo/xsinfo.adb ada/bldtools/sinfo/csinfo.adb cp -p /wrkdirs/usr/ports/lang/gcc6-aux/work/gcc-6-20170202/gcc/ada/sinfo.ads /wrkdirs/usr/ports/lang/gcc6-aux/work/gcc-6-20170202/gcc/ada/sinfo.adb /wrkdirs/usr/ports/lang/gcc6-aux/work/gcc-6-20170202/gcc/ada/xsinfo.adb /wrkdirs/usr/ports/lang/gcc6-aux/work/gcc-6-20170202/gcc/ada/csinfo.adb ada/bldtools/sinfo (cd ada/bldtools/sinfo; gnatmake -q xsinfo ; ./xsinfo sinfo.h ) raised STORAGE_ERROR : stack overflow or erroneous memory access gmake[3]: *** [/wrkdirs/usr/ports/lang/gcc6-aux/work/gcc-6-20170202/gcc/ada/Make-generated.in:45: ada/sinfo.h] Error 1
