[B2-devel] Reason(s) for capturing SIGSEGV? Also, VOSF?

[David L. <dl...@po...>]

Hello all,

I've been doing some work within the Basilisk II code, on Mac OS 10.12 +
Xcode 8.x.  I've been able to get it compiling, and almost limping along,
but have found some parts of the code to be a bit confusing.  In
particular, I was wondering if there is a reason, or a need, for the app to
try to capture SIGSEGV?  My guess on this has been that it is related to
emulation (to note, I am using the UAE virtual-CPU), but am not entirely
sure on this.

On a similar note, I also noticed some "VOSF" code, which appears to deal
with display code, on/after a segfault.  Might anyone has an idea what this
is, or was for?

I've tried digging through Basilisk's code, and its ChangeLog for clues,
but am still a bit hazy on these.  I'm wondering if they are necessary.

Cheers!
