gzipped C source code
The attached code, when compiled by gcc trunk dated 20161109 and the
compiler flags -fsanitize=kernel-address --param asan-stack=1 does
this
net/bluetooth/mgmt.c:5847:2: internal compiler error: in gimplify_switch_expr,
at gimplify.c:2272
0x99f9bb gimplify_switch_expr
../../trunk/gcc/gimplify.c:2272
0x99840d gimplify_expr(tree_node**, gimple**, gimple**, bool (*)(tree_node*),
int)
../../trunk/gcc/gimplify.c:11402

The source code is from the Linux kernel, so I assume it is quite
important to have it working.
I'll have a go at reducing the test case code.
