Subject: [libclang] Protect against the declaration's SourceRange being invalid
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=ed8bef44c0545fd55a78715606f8d733f6498b21;p=clang

[libclang] Protect against the declaration's SourceRange being invalid
before passing to RangeCompare.

Though no idea how this can occur with the decls returned from
findFileRegionDecls().
