I just tried to compile the package libhugetlbfs-2.5 with the GNU
C compiler version 4.5 snapshot 20091224 and the compiler said

n file included from /usr/include/string.h:640:0,
                 from icache-hygiene.c:37:
/usr/include/bits/string3.h: In function 'jumpfunc':
/usr/include/bits/string3.h:52:3: internal compiler error: in
emit_block_move_hints, at expr.c:1197
