State-Changed-Why:
    This is an optimization problem I was able to reproduce with C code.  I've refiled this case with some C code instead.  See optimization/4085.

>Description:

	Compiling the following with -fPIC -O2 produces code which
refers to non-existant labels.  Specifically, .L7 and .8 do not exist.
This is preventing a shared version of xerces from building and
running.

	.align 4
	.align 2

	.long .L8-.L10
	.long .L8-.L10
	.long .L8-.L10
	.long .L8-.L10
	.long .L8-.L10
	.long .L7-.L10
	.long .L8-.L10

        switch (attType) {
	case 0:
            attTypeString = "string";
        case 1:
            attTypeString = "ENTITY";;
