No, I haven't tried it elsewhere. My usual motivation to avoid that is
because there are tons of possible differences (toolchains, libs, cpu
architectures, kernels, patch sets to fix SoC issues) and it's next to
impossible to guarantee that the code and data have precisely the same
layout in memory, and that the code is executed precisely the same way.

But this is my perception, it's entirely OK if others see things in
different perspective :D.

Kind regards,
Nikolay
