I just tried it on a Linux box, and I can verify that it happens there
too.  I poked around a little, and found that the segfault happens at
line 237 of parse.y, when parsing the macro at line 75 of boot.inc:

UD_INIT	macro
	endm
UD_TX	macro	BYTE
	endm
UD_TXB	macro	BYTE
	endm

I stuck an instruction in the macro and it segfaulted in the second
macro; I stuck an instruction in that one and it stopped segfaulting:

UD_INIT	macro
	movlw	0
	endm
UD_TX	macro	BYTE
	movlw	0
	endm
UD_TXB	macro	BYTE
	endm

(that's right, I didn't need an instruction in the third empty macro).

So that's a workaround at some level....

Hi Joe,

thank you very much for digging this up for me.

As those macros seem to be for debugging
and empty I can just remove the invocations.

I should probably file a bug report.

Thanks again.
