What compiler are you testing with?  On what line is it reporting that
it has left the block?  I'd like to understand the difference before we
change this.

What about PowerPC targets which don't have an FPU?  Hmm, it looks like
GDB more or less assumes the FP is present.  Not sure about SPE though.
