Thanks for the core file, it is a similar bug as last time.

Can you please run these commands:
$ cd /tmp
$ sigtool --unpack-current bytecode
$ clambc -- --debug 767944.cbc 2>log

Then send me the file called 'log', make sure it contains CMOV, or
CMOVE, if not try another .cbc files from /tmp.

Crash is here:
Dump of assembler code from 0xb16e58ac to 0xb16e58b6:
=> 0xb16e58ac:   0f 44 f0       cmove  %eax,%esi
   0xb16e58af:   84 db  test   %bl,%bl
   0xb16e58b1:   0f 85 80 ff ff ff      jne    0xb16e5837

I don't understand why though, the pattern for CMOV is guarded by a
CPUID test.
Could you install the 'x86info' package, and run this (as root):
# modprobe cpuid
# x86info -a

And send me the output from x86info -a.

Best regards,
