Bug#763755: blender: SIGILL on startup

[Daniele Forsi]

Package: blender
Version: 2.71+dfsg1-1
Severity: important

Dear Maintainer,

could Blender be changed to check if it is running on a supported CPU and fail with a nicely informative error message?

On my PC blender is terminated on startup with:
Program received signal SIGILL, Illegal instruction.

Running in gdb I get this backtrace:
(gdb) bt
#0  0x09015ecd in RNA_def_property_range ()
#1  0x0901a304 in RNA_def_int ()
#2  0x084bce4c in ?? ()
#3  0x084c0657 in WM_operatortype_append ()
#4  0x084c5556 in wm_operatortype_init ()
#5  0x084b7f38 in WM_init ()
#6  0x08491dec in main ()

and this is the instruction that triggers the SIGILL:
(gdb) x/i $eip
=> 0x9015ecd <RNA_def_property_range+173>:	cvttsd2si (%esp),%ecx

I am using a dual Pentium 3 CPU system:
