[B2-devel] SheepShaver Segfault

[Klaus R. <kla...@rz...>]

Hi,

unfortunately SheepShaver crashes on current Ubuntu systems (master 
branch from https://github.com/cebix/macemu.git)
I could verify this on 32-bit as well as 64-bit systems.

Below the stacktrace. Any suggestion to debug this further?

Cheers
	Klaus
