I seem to recall very similar errors happening. I believe that ARM processors require 16 byte alignment or something. We've probably either missed doing so somewhere or had a regression.

Yes, I use to get this illegal instruction when we first started: 

0x002ff9b4 in decompress (c=251) at be_decompress.c:75  
75        d = (double)*(float *)string_ptr;

Which was fixed with: 

float f;  
d = (double)*(float*)memcpy((void*)&f, (void*)string_ptr, 4);

Jacques, for your illegal instruction, can you give this a try? 

... 
//--d= *(double *)string_ptr;  
memcpy(&d, (double *)string_ptr, 8); 
...

Thanks,
Ira
