Here the function mangle  is involved. Mangles/Names are part of 
the ABI in D specs: 
https://dlang.org/spec/abi.html#type_mangling, although you're 
right, generally speaking the ABI is rather what you described.

What's strange is that with a different mangle, the previous 
function that stand in the static library could still be linked 
but with different results. Usually this is not the case when the 
mangle changes. That's why this breakage is particularly 
"remarkable" i find.
