At least in g++ 3.4 this *feature* is still present. I remember a painful asm
debugging session where some registers went mad. The reason was I merged
couple of individual asm template sequences and forgot to place a \n at some
seam points and those instructions were simply ignored.
Lesson: always but a \n after asm template instructions, even or especially
after the last asm instruction.
