Oh, also some builds of crypt_blowfish (and of affected systems/apps)

typical systems).
Just to add that on some (perhaps all) ARM plateforms char is by
default: "unsigned" (unless you compile with -fsigned-char as you have
noted).

This is an old link that expose some problems when you just use 'char var'
on ARM (perhaps not only on ARM):
