These fail in the same place but fail for power 8, 9, and 10 little endian and power 8 big endian.

It's not clear to me what the testcase intends to test - it lacks a comment :/ c3d2600cfb476^ also exhibits this problem, so does d2a898666609^ so this problem must exist for longer time and it seems unrelated to this issue at hand. Can you properly bisect and open a different bugreport for this? ^ permalink raw reply [flat|nested] 5+ messages in thread
