Subject: Re: [9fans] plan9 go output faults on 9vx but ok on cpu
Date: Tue, 11 Jan 2011 19:03:18 +0200	[thread overview]

I'm typing from my phone so I don't have go sources in front of me,
but 0xdfffefc0 looks like the address I used for per thread G and M
structs - just bellow struct Tos.

Andrey and I also tried running on a 32-bit 9vx with the same effect.

Is 9vx using a different memory layout than Plan 9?
