Uninitialized variables in TComSlice

Reported by: csghone Owned by:
Priority: minor Milestone: HM-5.1
Component: HM Version: HM-5.0
Keywords: Cc: fbossen, ksuehring, davidf, jct-vc@…

Description

In case sliceMode=1, some variables are left uninitialized in second slice onwards leading to invalid access and crash.

List of variables:
m_RefPicListModification.m_bRefPicListModificationFlagL0
m_RefPicListModification.m_bRefPicListModificationFlagL1
m_RefPicListModification.m_uiNumberOfRefPicListModificationsL0
m_RefPicListModification.m_uiNumberOfRefPicListModificationsL1

This initialization is needed as part of TComSlice::copySliceInfo() as well to fix the problem for sliceMode=1.
