[Vm-dev] [StackVMUnix] Illegal Instruction

[Eliot Miranda]

Hi Bernardo,

    what kind of processor do you have?  Does it support sse2?  (it needs to
for Cog & Stack VMs).  Is 0x8187ef8 a valid address (e.g. what's the output
of x/10w 0x8187ef8)?  why are you not getting symbols in your backtrace?
 Are you stripping the VM by any chance?  If so, please don't.  Having
symbols would really help in debugging this; your stack trace has only the C
library entrypoint symbol.  The rest is raw addresses.
