2.4.0-test10 kernel/module.c
static struct module kernel_module = { size_of_struct: sizeof(struct module), name: "", uc: {ATOMIC_INIT(1)}, flags: MOD_RUNNING, syms: __start___ksymtab, ex_table_start: __start___ex_table, ex_table_end: __stop___ex_table
gcc 2.7.2.3 miscompiles structures that have internal labeled structure initializers. uc gets misaligned, ex_table_start is then misaligned and the exception table handling fails.
