Subject: Fix for http://llvm.org/PR23392: magick/feature.c from ImageMagick-6.9.1-2 ICEs.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f681a19b9cee2d6c1db6ef3d8155077562988dd4;p=clang

Fix for http://llvm.org/PR23392: magick/feature.c from ImageMagick-6.9.1-2 ICEs.
Fix for codegen of static variables declared inside of captured statements. Captured statements are actually a transparent DeclContexts, so we have to skip them when trying to get a mangled name for statics.
Differential Revision: http://reviews.llvm.org/D9522
