With recent kernels on HAMMER/amd64 I cannot complete a buildworld. The compilation keeps failing with problems like: cc -O2 -pipe -DBFD_DEFAULT_TARGET_SIZE=64 -I. -I/usr/src/gnu/usr.bin/binutils/as -I/usr/src/gnu/usr.bin/binutils/as/../libbfd -I/usr/obj/usr/src/tmp/usr/src/gnu/usr.bin/binutils/as/../libbfd -I/usr/src/gnu/usr.bin/binutils/as/../../../../contrib/binutils/include -DDEFAULT_ARCH=\"x86_64\" -DTARGET_CPU=\"x86_64\" -DTARGET_CANONICAL=\"x86_64-obrien-freebsd\" -DTARGET_ALIAS=\"x86_64-obrien-freebsd\" -DVERSION=\""2.15 [FreeBSD] 2004-05-23"\" -D_GNU_SOURCE -I/usr/src/gnu/usr.bin/binutils/as/../../../../contrib/binutils/gas -I/usr/src/gnu/usr.bin/binutils/as/../../../../contrib/binutils/gas/config -I/usr/src/gnu/usr.bin/binutils/as/../../../../contrib/binutils -I/usr/src/gnu/usr.bin/binutils/as -I/usr/src/gnu/usr.bin/binutils/as/amd64-freebsd -I/usr/obj/usr/src/tmp/legacy/usr/include -c /usr/src/gnu/usr.bin/binutils/as/../../../../contrib/binutils/gas/subsegs.c /usr/src/gnu/usr.bin/binutils/as/../../../../contrib/binutils/gas/subsegs.c: In function 'subseg_set_rest': /usr/src/gnu/usr.bin/binutils/as/../../../../contrib/binutils/gas/subsegs.c:205: internal compiler error: Bus error: 10 Please submit a full bug report, with preprocessed source if appropriate.
