Somewhat reduced testcase

Thread 2.1 "cc1plus" received signal SIGSEGV, Segmentation fault.
[Switching to process 24708]
cx_check_missing_mem_inits (fun=<optimized out>, body=0x3fffaf688268,

740               if (TREE_CODE (field) != FIELD_DECL
(gdb) p field
$1 = (tree) 0x0

Unfortunately reducing the testcase takes ages.
