Extended Description

I am running FreeBSD 10-stable and have just installed clang 3.7 from ports, after setting CC=clang37 etc in make.conf and trying to compile graphics/blender (2.75) I get an assertion failed error

Assertion failed: (!DMEntry && "Decl already exists in localdeclmap!"), function EmitAutoVarAlloca, file /wrkdirs/usr/ports/devel/llvm37/work/llvm-3.7.0rc1.src/tools/clang/lib/CodeGen/CGDecl.cpp, line 1016.

% uname -a
FreeBSD leader.local 10.2-PRERELEASE FreeBSD 10.2-PRERELEASE #​16 r285937: Tue Jul 28 20:58:13 ACST 2015 root@leader.local:/usr/obj/usr/src/sys/GENERIC amd64

% clang37 --version
clang version 3.7.0 (tags/RELEASE_370/rc1)
Target: x86_64-unknown-freebsd10.2
Thread model: posix

I have also tried with devel/llvm-devel
% clang-devel --version
clang version 3.8.0
Target: x86_64-unknown-freebsd10.2
Thread model: posix

debug files for both are available at http://shaneware.biz/freebsddebugdata/clang-debug

Reduced a bit:

$ clang -cc1 -triple x86_64-unknown-freebsd10.2 -emit-obj -fopenmp a.i

typedef struct BVHTree BVHTree;
typedef struct BVHTreeOverlap {
} BVHTreeOverlap;
typedef struct BVHNode { char totnode; } BVHNode;
struct BVHTree {
BVHNode **nodes;
int totleaf;
char tree_type;
} BVHOverlapData;
BVHTreeOverlap *BLI_bvhtree_overlap(BVHTree *tree1, BVHTree *tree2,
unsigned int *r_overlap_tot) {
int j;
#pragma omp parallel for private(j) schedule(static) if (tree1->totleaf > 1024)
for (j = 0; j < extension({
typeof(tree1->tree_type) a_ = (tree1->tree_type);
typeof(tree1->nodes[tree1->totleaf]->totnode) b_ =
(tree1->nodes[tree1->totleaf]->totnode);
((a_) < (b_) ? (a_) : (b_));
});
j++) {
}
}
