Subject: Make RegionStoreManager::InitializeArray safe against array sizes that don't have... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=500386194c73b7976894278a7da08ad9b59ec81e;p=clang

Make RegionStoreManager::InitializeArray safe against array sizes that don't have pointer width.
This may be the case on 64-bit systems. Whether that fact is a bug is a different question, but it's easy to cure the symptom.
