I can reproduce this on OS X 10.11.3:
sim> show version
VAX 11/780 simulator V4.0-0 Beta
Simulator Framework Capabilities:
64b data
64b addresses
Ethernet Packet transports:PCAP:TAP:NAT:UDP
Idle/Throttling support is available
Virtual Hard Disk (VHD) support
Asynchronous I/O support
FrontPanel API Version 2
Host Platform:
Compiler: GCC 4.2.1 Compatible Apple LLVM 7.0.2
(clang-700.1.81)
Simulator Compiled: Feb 17 2016 at 15:01:37
Memory Access: Little Endian
Memory Pointer Size: 64 bits
Large File (>2GB) support
SDL Video support: No Video Support
RegEx support for EXPECT commands
OS clock resolution: 1ms
Time taken by msleep(1): 2ms
OS: Darwin Shibaers-Mini.westell.com 15.3.0 Darwin Kernel
Version 15.3.0: Thu Dec 10 18:40:58 PST 2015;
root:xnu-3248.30.4~1/RELEASE_X86_64 x86_64
git commit id: aadd66c7
Switching to -O1 instead of -O2 doesn't make a difference. Switching to
-O0 gives a different error:
VAX 11/780 simulator V4.0-0 Beta git commit id: aadd66c7
libpcap version 1.5.3 - Apple version 54
Abort trap: 6
I'll see if I can narrow things down a little bit more. Michael, maybe
it's easiest to open a github issue for this so it can be tracked there?
