[cfe-commits] [PATCH] AstUnit::LoadFromCompilerInvocation

[Hurcan Solter]

Unlike LoadFromCommandLine, LoadFromCompilerInvocation(the one with many
arguments) causes a crash if Precompilepreamble is set to true because
there is no FileManager at that point. Two methods are not in sync despite
being very similar..
