Re: [B2-devel] Fixes for BasiliskII and SheepShaver for Mac OS X 10.4 and 10.5 ppc and intel

[Alexei S. <ale...@gm...>]

Hi Mike,

I've committed the first two patches you sent. Sorry it took so long,
but I've been really busy lately.

I know it's not related to your code, but looking at the code brought
up some serious concerns.

Particularly struct sigsegv_info_t that's re-declared would be
incomplete if HAVE_MACH_EXCEPTIONS is on.

I've added a big FIXME there, and haven't had the time to investigate
further - but if Screen_fault_handler ends up accessing the extra
fields in that struct - it will be a serious bug (accessing memory
past the end of that structure). This really needs to be fixed (again
it's not your changes, but still..)
