Interesingly, in test 18 and 19 there are same expected hashes however reulting strings does not match.

[pgajdos]

This is with 7.0.8-6.
@bastien-roucaries, do you experience the same?

[pgajdos]

(I experience the issue for a long time, see #1059)

[andreas-schwab]

It also fails on m68k, so my guess would be excess floating point precision.

We can't help. We do not have access to a i586 host and the unit tests pass on all of our development machines.
