This might just be a debug display artifact- I haven't
looked at the binary code dump, but I did modify
Emit_prologue and friends to leave a trail of bread crumbs
when called ( see log file below ), and I'm not seeing
the double calls there.
One other difference between the 0.25 and 0.29.1
outputs is that the initial __ghdl_malloc call for
0.29.1 is for 0x12, which is not aligned.
