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.
