Well, the function itself is properly aligned (so my fix didn't take effect anyway).

But the processor decoded the first instruction as 2-byte (thumb?), then increased PC by 2. And it raised SIGILL at

So, I guess
 - assembler emits a bad machine code for vpush
or
 - kernel is not configured properly to run vfp instructions

I'd like to look into objdump -d result to check the machine code.
