Thanks for trying!

Hm. That traces back to the meataxe function FfSetField, which gives a
error when it can neither read a stored multiplication table nor create
a new one.

A part of #20136 is related with finding the correct path to the
multiplication tables. So, perhaps it does fix it. Can you please try?

Just to make sure: Both systems are 32bit, right? Does meataxe work, if
you do *not* move the binary to a different platform but keep it on the
platform it was compiled with? Is sizeof(long) different on both
platforms? If it is different, then perhaps meataxe has sizeof(long)
hardcoded somewhere?
