Subject: When building source location information for an _Atomic type, be sure
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=43fe245b37c3cd36d837aab9eb98551328d30141;p=clang

When building source location information for an _Atomic type, be sure
to fill in the source locations for the underlying value type. Fixes
an intermittent crasher (due to uninitialized data) in the PCH test
for _Atomic types.
