x265 3.1_RC1+3-3bdf06e3c628 crash (--aq-motion , 2-pass, tune grain)

[Nikolas Raiser]

2-pass encoding with tune grain and aq-motion crashes instantly.

Always reproduceable.

‌

Testcase:

Try to encode a random video using the following parameters:

--pass 1 --bitrate 800 --tune grain --profile main10 --output-depth 10 --aq-motion --y4m

‌

Expected result: encoding

Actual result: crash

x265 3.1_RC1+3-3bdf06e3c628 failed with exit code: -1073741819 (0xC0000005)

The exit code might be a system error code: Die Anweisung in 0xp verwies auf Arbeitsspeicher bei 0xp. Der Vorgang s konnte im Arbeitsspeicher nicht durchgeführt werden.
