Subject: Initialize the non-trivial C union bits I added to RecordDeclBitfields
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=eba646b53dd71389216e9a36837fa204b934f8de;p=clang

Initialize the non-trivial C union bits I added to RecordDeclBitfields
in r365985

These bits weren't being initialized in the RecordDecl's constructor,
which probably caused test/Modules/stress1.cpp to fail on a couple of
bots.
