Following example gives an assertion failure, on linux-x86_64.

Just plain 'clang -S rte.c'
----------------  rte.c --------------
typedef char C1 __attribute__((__vector_size__(1)));
extern void *gptr;
typedef union { float f1; C1 f2; } U2;
void callee(U2 v) { *(U2*)gptr = v; };
----------------------------------------

clang version 3.8.0 (trunk 242488)
Target: x86_64-unknown-linux-gnu

/llvm/tools/clang/lib/CodeGen/TargetInfo.cpp:1821: static
{anonymous}::X86_64ABIInfo::Class
{anonymous}::X86_64ABIInfo::merge({anonymous}::X86_64ABIInfo::Class,
{anonymous}::X86_64ABIInfo::Class): Assertion `(Accum != Memory && Accum !=
ComplexX87) && "Invalid accumulated classification during merge."' failed
