Subject: Teach libclang to be more careful around BlockDecls, and don't assume
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=13c8ccb59b38e9e7133f1c80a00f210b6514a0b1;p=clang

Teach libclang to be more careful around BlockDecls, and don't assume
that a TypeSourceInfo is always available, like we do everywhere else
in libclang. Fixes <rdar://problem/9311140>.
